SKF 61826-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 130x165x18mm

The SKF 61826-2RS1 sealed thin-section deep groove ball bearing provides support for large-diameter rotating shafts without the substantial housing dimensions associated with wider bearing series. Its 618 series geometry combines a large shaft opening with an exceptionally narrow bearing section, making it useful where compact construction is more important than maximum load capacity. The single row ball arrangement accommodates radial loads and axial forces in either direction within its design limits. SKF catalogue specifications give a basic dynamic load rating of 37.7kN and a basic static load rating of 43kN. These values allow engineers to evaluate bearing suitability against the expected duty cycle, including periods of slow rotation or stationary loading.

The 2RS1 rubber contact seals retain factory grease and help restrict dust and moisture from reaching the rolling elements. This is particularly useful in enclosed rotary equipment where external lubrication arrangements are difficult to accommodate. SKF specifies a limiting speed of 2,200rpm for this sealed version, making seal friction and running temperature relevant selection factors. Normal radial internal clearance must be assessed alongside shaft interference fits, housing tolerances and thermal expansion. Because the bearing rings are relatively thin for their diameter, uniform housing support and carefully controlled mounting forces are important. Compared with the non-contact sealed 61826-2RZ, this version prioritises contact sealing rather than lower running friction.

Typical Applications:

Large-diameter rotary positioning assemblies

Space-restricted industrial shaft supports

Specialised automation and indexing machinery

Lightly loaded rotary equipment with large bores

Compact industrial mechanisms requiring sealed bearings
