LONG-LIFE SEALED SPHERICAL ROLLER BEARINGS FOR CONVEYOR PULLEY IN THE MINING INDUSTRY

Product catalog summary

Introduction
NSK has developed a series of long-life sealed spherical roller bearings (SSRB) specifically designed for conveyor pulley applications in the mining industry. These bearings are engineered to withstand the harsh and contaminated environments typical in mining operations, offering increased uptime and reliability.

Proven Benefits

Utilization of NSK's Tough Steel for extended service life in contaminated conditions.
High-performance seal design that compensates for bearing misalignment.
Removable seal allows for internal clearance measurement during installation.
Easy installation with bolt-fastened seals.
Dimensionally interchangeable with conventional spherical roller bearings.

Design Features

Bearing Boundary Dimension: SSRB maintains the same boundary dimensions as standard bearings, often with a higher load capacity (Cr).
Special Bearing Material & Heat Treatment: Tougher steel is used for the inner and outer rings to extend bearing life and prevent wear under poor lubrication conditions.
Seal Design: Features an integral garter spring for high sealing performance, with hydrogenated nitrile butadiene rubber tolerating temperatures up to 100ºC. The seal lip contacts the bearing inner ring, and the seal holder is easily bolt-fastened to the outer ring.

Technical Specifications
The document provides a detailed table of SSRB specifications, including reference numbers, load capacities (Cr and Cor), dimensions (d, D, B), and speed limits (rpm) for various bearing sizes.
