Decoding SKF 6210-2RS1K
- 62Series
- Deep groove ball bearings, 62 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- 2RS1KSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6210 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6210-2RS1K measures 50 mm across the bore and 90 mm across the outside diameter; its width is 20 mm (50 x 90 x 20 mm).

The SKF 62..-2RS1K is a single row deep groove ball bearing that combines two features: contact seals on both sides and a tapered bore. It suits equipment where the shaft is tapered and the bearing must stay protected from dust and moisture. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams across the United States and Latin America.
Reading the code: the 62 block identifies a medium section series, so for a given bore the outer diameter and width are larger than those of series 60. The 2RS1 suffix means contact elastomer seals on both faces, which keep the factory grease in and keep contaminants out. The K at the end marks a tapered bore, typically 1:12, for mounting on a tapered shaft or with an adapter sleeve. Typical part numbers include 6206-2RS1K, 6207-2RS1K, 6208-2RS1K, 6209-2RS1K and 6210-2RS1K.
Where these bearings fit: gearboxes, conveyors, food processing machines, packaging lines, fans, pumps and agricultural equipment. The 2RS1 seal is useful in humid or dusty plants because it limits grease loss and blocks particles. The tapered bore allows a controlled interference fit and easier disassembly than a cylindrical bore in many cases.
Selection notes: deep groove ball bearings handle moderate radial and axial loads, and the 62 series takes more load than the 60 series because of its larger section. The 2RS1 version is lubricated for life and needs no relubrication, but it is not intended for very high speeds or extreme temperatures. With a K bore, mounting must be precise: use a lock nut and lock washer or an adapter, and check radial clearance after tightening. Shaft and housing alignment between supports also matters to avoid extra loads.
Interchange: each manufacturer uses its own suffixes, so a 2RS1 from SKF may be listed as 2RS, 2RSR or something similar elsewhere. Seal material, internal clearance and tolerances can differ. Before substituting, confirm bore, outer diameter, width, seal type and taper. If you send the original code, our team can suggest equivalents and help you choose.

Frequently asked questions
- SKF 6210-2RS1K bearing: what are its dimensions?
- SKF 6210-2RS1K measures 50 mm across the bore and 90 mm across the outside diameter; its width is 20 mm (50 x 90 x 20 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6210.
- What does 2RS1 mean on an SKF bearing?
- 2RS1 identifies contact elastomer seals on both sides. They retain the factory grease and block dust, water and other contaminants, making the bearing suitable for dirty or humid environments.
- Why does the bore have a K suffix?
- K indicates a tapered bore, usually 1:12. It allows mounting on a tapered shaft or with an adapter sleeve to achieve a controlled interference fit and easier disassembly.
- Can I interchange a 6206-2RS1K with another brand?
- Possibly, but verify bore, outer diameter, width, seal type and taper. Nomenclatures differ between manufacturers. If unsure, send us the original code and we will help you find a match.
