Deep Groove Ball Bearings SKF 6334 M

The SKF 6334 M single-row deep groove ball bearing (170x360x72 mm) features a solid brass cage for heavy-duty industrial radial applications.

The SKF 6334 M single-row deep groove ball bearing, as an open rolling bearing, primarily accommodates radial loads as well as moderate axial loads in both directions. Manufactured from standard rolling-bearing steel (100Cr6) with dimensions of 170 mm bore, 360 mm outer diameter and 72 mm width, this design is engineered for heavily loaded large machinery. The bearing has standard radial clearance and complies with tolerance class P0/PN (ABEC 1). Its standardised geometry facilitates integration into standardised bearing seats in continuous industrial operation.

What is the 6334 M deep groove ball bearing suitable for in industrial applications?

This large bearing is primarily used in heavy-duty mechanical engineering and in heavily loaded industrial drives. With dimensions of 170 × 360 × 72 mm, the rolling bearing can withstand considerable mechanical forces. As an open design without sliding seal discs, lubrication is supplied directly via the surrounding system using grease or oil. The bearing covers a temperature range from –20 to +150 degrees Celsius and enables continuous rotational speeds with stable heat dissipation.

What are the distinctive features of the brass cage in the 6334 M deep-groove ball bearing?

Compared to sheet steel cages, the built-in brass cage (designation M) is characterised by high strength and favourable free-running properties. It reliably guides the rolling elements during vibrations, high accelerations or alternating shock loads. In combination with the standard radial bearing clearance, the bearing is suitable for operating conditions involving uniform heating between the shaft and housing. The outer ring is designed without a groove or flange, which is why axial fixation must be achieved via the housing.
