The NATR/NATV series are high-performance supported roller bearings designed for heavy radial loads, slight axial loads, and angular misalignment. Featuring either a needle roller and cage assembly (NATR) or full complement needle rollers (NATV), they deliver high rigidity and load-bearing capacity. Constructed from GCr15 bearing steel with hardened raceways for superior wear resistance, these bearings are available with single or double contact seals (PP) to ensure reliable operation in dusty and harsh environments. Widely applied in cam drives, conveyor systems, and machine tool guides, they are ideal for automation equipment and mechanical transmission applications where reliability and longevity are critical.

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.

Structural Characteristics: The Dual Advantages of Full-Complement Rollers and an Spherical Outer Ring Design

The core design of spherical outer ring, full-complement cylindrical roller bearings incorporates two major innovations: a full-complement roller structure and a spherical self-aligning function.

1. Full-Complement Roller Design: Unlike traditional bearings that utilize a cage, the SL05/06 series eliminates the cage to fill the raceway entirely with cylindrical rollers, thereby increasing the roller count by approximately 20% to 30%. This design significantly enhances the bearing's radial load capacity, making it particularly suitable for applications involving high impact and vibration—such as mining machinery and port cranes.

2. Spherical Self-Aligning Function: The bearing's outer ring features a spherical design that mates with a spherical housing seat, automatically compensating for misalignment between the shaft and the housing bore (typically allowing for an angular error of ≤2°). This feature effectively reduces the precision requirements for installation and accommodates shaft deflection under dynamic operating conditions, thereby extending the service life of the equipment.
