Timken Cylindrical Roller Bearings Guide
Product Description
The NU31/500EMA Timken single row cylindrical roller bearing consists of an inner ring, an outer ring, a single row of cylindrical rollers, and a cage. The cylindrical roller design provides a large contact area between rollers and raceways, delivering high radial load capacity, excellent rigidity, and reliable performance under heavy radial loads. The separable inner and outer ring design allows convenient installation, inspection, and maintenance, while the optimized roller guidance system helps ensure stable operation at high speeds and demanding working conditions.
The NU31/500EMA bearing is widely used in power generation equipment, gear drives, pumps, rolling mills, wind energy systems, and other industrial equipment. It is particularly suitable for applications requiring high radial load capacity, high-speed operation, precise positioning, and long service life under continuous industrial operation.
