These bearings offer smooth, low-friction linear motion with high precision and load-carrying capacity, housed in a durable mounting block for easy installation in a wide range of applications.

High-Load Mounted Linear Ball Bearings

These bearings deliver robust, low-friction linear motion with enhanced load-bearing capacity, ensuring stability and durability in demanding applications with heavy loads.

Corrosion-Resistant Mounted Linear Ball Bearings

These bearings provide reliable, smooth linear motion in harsh environments, with materials and coatings designed to withstand exposure to moisture, chemicals, and other corrosive elements, ensuring long-term durability.

Adjustable Mounted Linear Ball Bearings

These bearings offer customizable clearance and preload settings, allowing for precise alignment and smooth linear motion, making them ideal for applications requiring fine-tuning of bearing fit and performance.

Flange-Mounted Linear Ball Bearings

These bearings provide smooth, precise linear motion with easy installation and secure mounting, thanks to their integrated flange design, making them ideal for stable and reliable use in various industrial and automation applications.

Corrosion-Resistant Flange-Mounted Linear Ball Bearings

These bearings offer smooth, precise linear motion with durable, rust-resistant materials and coatings, ensuring reliable performance and easy installation in harsh, corrosive environments.

Mounted linear ball bearings integrate a recirculating ball bushing into a ready-to-install mounting block, so the unit bolts directly onto a machine frame without custom housing machining. The shaft passes through the bearing, balls recirculate along the raceway to convert sliding friction into rolling friction, delivering smooth, low-friction linear motion with lower wear than plain bushings.

Key Benefits:

Fast installation — no custom bore machining required
Smooth, precise linear travel with reduced noise and wear
Available in multiple configurations for different loads and environments
Compatible with standard linear shafting for easy integration and replacement

Configurations Available:

Standard open/closed types for general motion control · High-load variants with reinforced ball circuits for heavier loads · Corrosion-resistant stainless/coated options for washdown environments · Flange-mounted styles for compact or vertical installations · Adjustable units for fine-tuned clearance and preload

Common Applications:

CNC machines and 3D printers · Packaging and labeling equipment · Semiconductor and electronics assembly · Medical diagnostic equipment · Factory automation and pick-and-place systems

What's the difference between a mounted linear ball bearing and a linear bushing?

A linear bushing needs a machined housing; a mounted unit already includes the mounting block, so it bolts straight onto a flat surface without additional machining.

How much radial load can these bearings handle?

Load capacity depends on series and bore size — standard units suit light-to-moderate loads, while high-load variants handle heavier carriage weights. Check the specific part's datasheet for exact ratings.

Are they suitable for wet or washdown environments?

Standard carbon steel units are not recommended for wet or corrosive conditions. Choose stainless steel or coated corrosion-resistant versions instead.

Do they require lubrication?

Yes — units ship with initial grease, but periodic re-lubrication is recommended, especially in high-cycle or dusty environments.

Can flange-mounted units replace block-style units?

Not directly — bolt pattern and mounting orientation differ. Confirm bolt spacing against your machine frame before substituting.
