Angular Contact Ball B. SKF 7310 BEP

The SKF 7310-bep angular contact ball bearing is designed to withstand combined loads and has an outer diameter of 110 mm and a width of 27 mm.

The single-row angular contact ball bearing 7310-bep from SKF Rolling Bearings accommodates radial forces as well as axial forces in one direction. Manufactured from standard rolling bearing steel, this design is characterised by dimensionally stable rings and guided rolling elements. With an outer diameter of 110 mm and a width of 27 mm, this open bearing is suitable for designs that utilise a continuous lubricant supply throughout the entire system. Thanks to the standard radial clearance, the bearing maintains its intended guidance accuracy under normal operating conditions.

What is the 7310-bep angular contact ball bearing suitable for?

This single-row bearing is suitable for shaft mountings where, in addition to radial forces, unidirectional axial loads are also present. Often, two single-row angular contact ball bearings are mounted in pairs facing each other to accommodate axial forces in both directions. As this is an open rolling bearing without integrated sealing rings, operation requires a clean installation environment and an external lubricant supply, for example via an oil bath or grease lubrication system.

What are the key features of the bearing’s polyamide cage?

The integrated polyamide cage guides the rolling elements with low internal friction and promotes smooth running of the unit. A temperature range of –20 to +120 °C is specified for the complete system, which is defined by the cage material and the rolling bearing steel. When designing the system, engineers and maintenance personnel should check whether the lubricant used is compatible with the cage material. Furthermore, the standard radial bearing clearance determines the operating clearance when the unit is installed; therefore, thermal expansion should be taken into account when selecting the fit.
