Deep Groove Ball Bearings FAG 6315 -2Z

The 6315-2Z deep-groove ball bearing from FAG Wälzlager, measuring 75 x 160 x 37 mm, features sheet metal shields on both sides and offers a high load-carrying capacity for industrial shaft mountings.

The 6315-2Z deep groove ball bearing is a single-row rolling bearing for industrial machinery and drive systems. With a bore of 75 mm, an outside diameter of 160 mm and a width of 37 mm, this design primarily accommodates radial loads as well as moderate axial forces. Manufactured from standard roller bearing steel 100Cr6 and fitted with a sheet steel cage, this FAG roller bearing model is suitable for operating temperatures ranging from -30 to +120 degrees Celsius.

What is the 6315-2Z deep groove ball bearing suitable for in mechanical engineering?

This rolling bearing is suitable for rotating shafts in industrial drives and power units. The non-contact gap seal between the two end plates keeps the frictional torque low, which helps to minimise heat build-up. Designs operating at medium to high speeds and subject to moderate dust exposure utilise this low-maintenance bearing arrangement, as the grease filling remains inside.

What are the advantages of the 2Z cover plates and standard bearing clearance?

The -2Z designation refers to two pressed-in cover plates made of profiled sheet steel. These gap covers keep solid particles away from the rolling elements without causing friction losses, as is the case with sliding lip seals. The standard radial bearing clearance ensures smooth running under normal installation conditions and at ambient temperatures of up to 120 degrees Celsius. Manufacture to tolerance class P0 (ABEC 1) ensures a dimensionally accurate fit on standard shafts.
