Attributes of UltraSlim Thin Section Bearings
Types: Angular Contact(Type-A), Four Point Contact(Type-X), Radial Contact(Type-C)
In applications with high axial loads, Type-A UltraSlim Thin Section Bearings, that is, angular contact ultra slim section bearings, should be used. These bearings also work well in radial or combined radial-thrust applications. The Type-A UltraSlim Thin Section Bearings should never be used alone to support moment loads or reversing axial loading. Two Type-A Ultra-thin Bearings are often used as a duplex pair.
The Type-X UltraSlim Thin Section Bearings, that is, the 4-point contact super thin section bearings, are ideal for moment loading. Type-X UltraSlim Thin Section Bearings are designed with gothic arch raceways creating 4 contact points between the balls and the raceways. This design is excellent for moment loading and reversing axial loading. The Type-X UltraSlim Thin Section Bearings can be used for other light loading conditions, but is not recommended in place of the Type-C or Type-A Ultra-thin section bearings for pure radial loads.
The Type-C UltraSlim Thin Section Bearings, that is, the radial contact super-thin section bearings, is designed with deep ball grooves to withstand high loads. Although these bearings are used primarily in applications with radial loads, they can withstand moderate axial loads, reversing axial loads, and moment loads.
Materials: Chrome Steel, Stainless Steel, Ceramic Hybrid
The standard UltraSlim Thin Section Bearings shown in the catalog have SAE 52100 steel rings and balls. UltraSlim Thin Section Bearings can be manufactured from other specialty bearing steels to provide corrosion resistance, high temperature capability, alternative load capacity or chemical compatibility.
LILY has manufactured UltraSlim Thin Section Bearings from SAE 440C stainless steel to provide corrosion resistance. As an alternative to stainless steel rings, the entire surface of the rings can be plated with nodular thin dense chrome (TDC). This plating, which meets AMS 2438, achieves a molecular bond that will not flake, peel or separate from the base material. The TDC plate has a hardness of HRC 70 - 78 and can withstand temperatures well beyond the range of the base material.
Some special UltraSlim Thin Section Bearings have been manufactured from Aluminum, 300 Series Stainless Steel, 17-4 Stainless Steel, and other metals.
Some special ball materials available include 440C Stainless Steel, 300 Series Stainless Steel, Silicon Nitride and M-50 Steel.
Precision: ABEC-1 to ABEC-7
UltraSlim Thin Section Bearings are available in four precision grades. ABEC grades 1, 3, 5 and 7 respectively. The tolerances for the bearing bores, outer diameters and radial plays are shown in the products tables.
UltraSlim Thin Section Bearings are 2.5 mm wide, available in bore sizes ranging from 35 mm to 170 mm for an array of applications requiring compact motion control design components.
Seal Type: Open
UltraSlim Thin Section Bearings are open-typed and they are usually oil lubricated, with low starting torque and flexible rotation.
Construction: constant section
The cross-section remains constant even in the case of larger shaft and housing bore diameters, therefore the UltraSlim Thin Section Bearings are also described as constant section (CS) bearings. There are three configurations of UltraSlim Thin Section Bearings. They are angular contact UltraSlim Thin Section Bearings (Type A), Conrad assembled deep groove radial UltraSlim Thin Section Bearings (Type C), and four-point contact radial UltraSlim Thin Section Bearings (Type X).
System of Measurement
The measurement system of UltraSlim Thin Section Bearings in the following catalog is the metric system.
Cage materials of UltraSlim Thin Section Bearings cover brass, nylon, phenolic and stainless steel.
Many different lubricants are available from LILY Bearing for special applications. Greases which are designed specifically for high speed, low torque, water resistance, high temperature, oscillatory motion and food machinery can be provided. Additional lubricants, such as dry film, are suitable for use in vacuums and space applications. For more details, please refer to the website of Ball Bearing Lubrication.
UltraSlim Thin Section Bearings with Normal chrome steel 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 be reduced. By means of special heat treatment processes and the addition of high temperature grease, we can also customize ultra slim section bearings for high temperature resistance.
Internal clearance is the play between outer ring, inner ring and rolling element of bearings. Generally, the amount of up and down movement of the outer ring with respect to the fixed inner ring is called the radial internal clearance and its right and left movement the axial internal clearance. Bearing internal clearance in operation is an important factor that has a significant influence on other factors such as noise, vibration, heat and fatigue life.
