KR22-PP is a stud-type cam follower needle roller bearing with 22mm outer diameter and M10 threaded stud.

It features a thick-walled outer ring, full complement needle rollers, and double-sided sealing (-PP/-2RS) for dust and water protection, with relubrication via the stud.

Offering high radial load capacity, resistance to misalignment and impact, low friction and smooth operation, it is a direct interchange for CF10.

Widely applied in automation lines, conveyor tracks, cam mechanisms, machine tools, packaging and textile machinery, it ensures stable performance, easy installation, high reliability and extended service life in heavy-duty continuous working conditions.

The NUKR90 and NUKRE90 series studded cam followers (track rollers) are designed for smooth rolling on a variety of tracks.

They feature a double-row full-complement cylindrical roller construction, using solid threaded studs instead of inner rings, and are equipped with a thick-walled outer ring with a curved running surface.

The NUKRE90 includes an eccentric ring for easy clearance adjustment, while the NUKR90 does not.

These bearings are pre-sealed for direct mounting and support lubrication via the studs, extending their service life. They are widely used in cam drives, conveyor systems, automated machinery, and other heavy-duty applications.

NUKR90 and NUKRE90 are used in the GBR90/GER90 series guide rail roller boxes.

The GBR90/GER90 series guideway roller housings (cam follower housings) are designed for heavy-duty linear motion in gantry robots and automated machinery.

They integrate multiple studded cam followers (Ø90mm) into a precision-machined housing, providing high rigidity, smooth rolling, and precise positioning on rectangular guideways. They are ideal for long-stroke, high-load applications such as gantry handling and industrial automation.

NUKR/NUKRE/PWKR/PWKRE Series Cam follower Stud Type Roller Bearings.

E means with eccentric collar.

This series bearings consist of double row full complement cylindrical roller bearings and shafts,

which are used in cam drives, conveyor systems,transmission system.

Stainless steel bearings are manufactured from corrosion-resistant materials including 304 and 440C stainless steel.

They feature excellent resistance to moisture, rust, acid, alkali and salt spray, making them ideal for harsh and humid environments.

With stable performance, high durability and low friction, these bearings are widely used in food machinery, pharmaceutical equipment, marine applications, packaging lines and automation systems.

Available in ball bearings, roller bearings and bolt-type cam followers, they ensure smooth operation and long service life in clean, corrosive or outdoor working conditions.
