KT Series Thin Section Tapered Roller Bearings

KT Series Thin Section Tapered Roller Bearings are widely used in many applications. They consist of a tapered inner ring assembly and an outer ring. Even under the most severe conditions, KT Series Thin Section Tapered Roller Bearings can bear both radial and axial loads with ease and provides low friction during operation. KT Series Thin Section Tapered Roller Bearings are suitable for thousands of applications. Lily Bearing can provide customised geometries, engineered surfaces as well as specialised sealing solutions for KT Series Thin Section Tapered Roller Bearings. The following catalog offers the data of KT Series Thin Section Tapered Roller Bearings, including size selection, price inquiry and CAD drawings for free download. 

Design Attributes of KT Series Thin Section Tapered Roller Bearings

KT Series Thin Section Tapered Roller Bearings are designed to accommodate combined loads, i.e. radial and axial loads acting simultaneously. The extensions of the raceways intersect at the same point on the bearing axis to realize real rolling. Thus, KT Series Thin Section Tapered Roller Bearings have low frictional torque during operation. The axial load capacity of KT Series Thin Section Tapered Roller Bearings increases as the contact angle α increases. The size of the contact angle (usually 10° to 30°) is related to the calculated coefficient e. The larger the value of e, the larger the contact angle.

Lily’s KT Series Thin Section Tapered Roller Bearings are characterized by light weight, thin walls and large bores. These bearings have large load carrying capacity and the advantages of thin section ball bearings. KT Series Thin Section Tapered Roller Bearings are single row radial type bearings, which are designed mainly for radial load applications.

The rolling elements of KT Series Thin Section Tapered Roller Bearings are retained by cages. According to the bearing setting, the contact angle of KT Series Thin Section Tapered Roller Bearings is about 12° under axial force, so they can bear thrust loads of reasonable sizes. These thrust loads are one-way direction, and they are achieved by the axial forces applied to the thicker end face. Similar to angular contact ball bearings, KT Series Thin Section Tapered Roller Bearings are usually mounted symmetrically with another bearing (usually of similar construction) so that the axial force to establish and maintain the contact angle can be provided. The two bearings can be mounted with the contact line intersection on the outside of the bearing (back-to-back) or on the inside (facing while). The former is more stable under overturning loads.

Material: chrome steel, stainless steel

Chrome steel is the most common material used for KT Series Thin Section Tapered Roller Bearings because of its characteristics of high load capacity and low noise. When clients needs the rust prevention,

the 440c stainless steel is recommended. Such stainless steel can withstand high load and high speed at the same time and the material also has the function of rust prevention.

Precision: ABEC-1 to ABEC-5

Factors to be considered when choosing an ABEC grade include radial and axial runout requirements, bore and OD fits, and the audible noise level. Lily Bearing offer these types of grades which show the available selection of bore and OD size tolerances, and the radial runout limits for each. ABEC of Grades 3 is the first choice for routine applications. Typically, race finish and race geometry are superior in ABEC 5. These grades are generally recommended generally for precision assemblies where low noise, minimal runout, and long life are important considerations for KT Series Thin Section Tapered Roller Bearings.

Sizing:  ID 177.80mm to 508.00mm  ( 7in. to 20 in.)

Sealing types

There are several sealing types of KT Series Thin Section Tapered Roller Bearings. They are open type KT Series Thin Section Tapered Roller Bearings, sealed type (rubber seal) KT Series Thin Section Tapered Roller Bearings as well as shielded type (metal shield) KT Series Thin Section Tapered Roller Bearings. Open type KT Series Thin Section Tapered Roller Bearings are the most common, while other seal categories require customization.

Features and advantages of KT Series Thin Section Tapered Roller Bearings 

Low Friction

The optimized roller designs on the retaining edges and the surface finish of the retaining edges can promote the formation of a lubricant film, thus reducing friction. This can reduce the heat generated by friction and the wear of the flange. In addition, KT Series Thin Section Tapered Roller Bearings can better maintain preload and reduce noise levels during operation.

Long service life

Convexity raceways, in detail, the shape of logarithmic raceways  of KT Series Thin Section Tapered Roller Bearings can optimizes load distribution along the contact surface, reduces stress peaks at the roller ends, and reduces sensitivity to misalignment and shaft deflection.

Improved operational reliability

The optimized surface treatment of the contact surface between the roller and the raceway can facilitate the formation of the fluid dynamic pressure lubricant film.

Consistency of roller profiles and dimensions

The rollers, which are integrated in KT Series Thin Section Tapered Roller Bearings, are manufactured to extremely precise tolerances and dimensional accuracy, so much so that they are almost identical. This provides optimum load distribution in KT Series Thin Section Tapered Roller Bearings, reduces the noise and vibration levels, and enables more precise preload.

Rigid bearing applications

In a certain application, a single row tapered roller bearing is often required to be adjusted in conjunction with another tapered roller bearing. Rigid bearing applications can be achieved by applying a preload.

Running-in period with peak temperature drop

KT Series Thin Section Tapered Roller Bearings usually have a running-in period. During this period, the KT Series Thin Section Tapered Roller Bearings for the conventional design mode experience a lot of friction which might result in wear. This will cause the bearing temperature to rise.

Provided that the bearings are correctly mounted and effectively lubricated, Lily Bearing can offer you the best solution. The solution can significantly reduce the friction, the wear during operation and the large amount of heat generated during friction.

Separability and interchangeability

KT Series Thin Section Tapered Roller Bearings are separable in design. The inner ring (tapered inner ring) with the roller and cage assembly can be mounted separately from the outer ring (tapered outer ring). In addition, tapered roller bearing components of the same size can be fully interchangeable. These characters can help mounting, dismounting as well as maintenance inspection operate smoothly.

System of Measurement: Inch

Lubrication: Factory Lubrication From a Stock of Several Hundred Lubricants

As the lubrication expert trusted by grease manufacturers, we know how important it is to find the right grease for your bearing application. With over 20 years of experience and knowledge, we are confident that we can match the best lubrication solution for our clients. What’s more, we can also use client-specified oil or grease lubricants.

Temperatures

Normal chrome steel KT Series Thin Section Tapered Roller Bearings can be used at constant temperatures of 120°C or intermittent temperatures of up to 150°C. Above these temperatures, the load capacity of the chrome steel will reduce. By means of special heat treatment processes and the addition of high temperature grease, we can also customize KT Series Thin Section Tapered Roller Bearings for high temperature resistance.
