INA SL045008-PP 40 mm ID Roller Bearing, 68 mm OD

This roller bearing is a high-performance component specifically designed to endure heavy loads and facilitate smooth motion. Featuring a cylindrical shape, it boasts an inside diameter of 40mm and an outside diameter of 68mm. Constructed from robust steel, this sealed roller bearing is capable of withstanding the rigours of various demanding applications while maintaining operational efficiency.

• Dual-row configuration enhances load distribution and stability

• Used for machinery requiring robust load support

The sealed design prevents the ingress of dirt and moisture, significantly reducing wear and tear while ensuring optimal operation in harsh environments.

Regular greasing is suggested, as this bearing can achieve a maximum speed of 3,150 rpm when properly lubricated, ensuring longevity and efficiency in its application.

Double row configurations offer superior stability and load capacity, making them ideal for applications with high axial and radial load requirements.

The combination of its high load capacity, appropriate sealing, and construction material facilitates efficient performance in diverse applications while minimising maintenance needs.

INA from Schaeffler bearings have solid outer and inner rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have high radial load carrying capacity, high rigidity and are suitable for compact designs. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage.;Cable sheave bearings (cylindrical roller bearings with snap ring grooves) are locating bearings. These bearings are rigid and can support moderate axial forces in both directions and high radial forces. They consist of solid outer and inner rings with ribs, rib-guided cylindrical rollers and sealing rings.;The outer rings have snap ring grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and held together by a rolled-in steel strip.

• Lower operating costs;• Reduced maintenance due to improved lubrication;• Lower heat generation;• Less noise

The bearings have higher load carrying capacity and longer life for the same dimensioning. In certain applications, a smaller bearing arrangement can be designed.
