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.

NUTR35 yoke type track roller is a reliable solution for demanding industrial environments where high load capacity, durability and precision are critical.

Featuring a double row full complement cylindrical roller structure and a thick‑walled outer ring, it is equipped with labyrinth seals on both sides for excellent contamination resistance.

This design ensures high radial load capacity, long service life and low maintenance requirements, making it perfectly suitable for continuous operation in conveyor systems, cam drives and heavy‑duty track support applications.

The NNTR5013065 is a heavy-duty double-row track roller bearing. With an inner diameter of 50mm, an outer diameter of 130mm, and a width of 65mm, it is designed to withstand extremely high radial loads, moderate axial loads, and heavy impact conditions.

Utilizing a cageless full roll configuration, it significantly improves load-carrying capacity and service life compared to standard roller bearings. The convex outer ring effectively compensates for slight misalignment and edge stresses, ensuring stable rolling performance.

This bearing features high rigidity, low friction, and stable operation, and is widely used in heavy-duty conveyor systems, lifting platforms, construction machinery, metallurgical equipment, automated production lines, tracked mechanisms, and other industrial applications. We provide reliable OEM and customization services and maintain strict quality control to meet the needs of global industrial applications.

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.

NUTR/PWTR series yoke type track rollers are engineered with full-complement cylindrical rollers, delivering superior load capacity and rigidity. Integrated ribs ensure precise axial guidance, while advanced sealing mechanisms guarantee reliable performance in harsh environments. Ideal for heavy-duty applications requiring exceptional precision and impact resistance.

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.

NNTR series bearings are heavy-duty roller bearings with thick outer ring, converging or curved outer diameters, and a full complement of cylindrical rollers. These bearings are primarily used in sliding tracks on heavy machinery, such as conveyor tracks, where they can roll directly on the raceways and withstand heavy loads and shocks. NNTR bearings typically feature epoxy guides and sparse seals, making them particularly suitable for large-scale transmission equipment.
