SKF 61828-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 140x175x18mm

The SKF 61828-2RS1 sealed thin-section deep groove ball bearing is engineered for large-diameter rotating equipment where housing diameter and axial width must be minimised. Its 618 series design provides a radial section of just 17.5mm around a substantial shaft bore, offering a space-efficient alternative to wider deep groove ball bearing series. The single row ball arrangement supports radial loads and accommodates axial forces in either direction within its rated limits. SKF specifies a basic dynamic load rating of 39kN and a basic static load rating of 46.5kN. The higher static rating is particularly relevant when evaluating stationary or slowly rotating loading conditions, but both ratings must be considered alongside the actual duty cycle and required bearing life.

The 2RS1 double rubber contact seals retain factory grease and reduce the entry of dust and moisture, making the bearing useful in large enclosed assemblies where routine relubrication access is restricted. SKF lists a limiting speed of 2,000rpm for this sealed version, reflecting the importance of seal friction and heat generation in a bearing of this diameter. Normal radial internal clearance requires careful assessment of shaft interference fits, housing geometry and operating temperatures. Because the rings are relatively thin for their diameter, mounting accuracy and uniform housing support are particularly important. This bearing should be selected for its specific dimensional envelope and verified loading requirements rather than as a direct substitute for a heavier series.

Typical Applications:

Large-diameter rotary positioning assemblies

Space-restricted industrial shaft supports

Specialised automation and indexing equipment

Lightly loaded large rotary mechanisms

Industrial equipment with compact bearing housings
