The SKF deep groove ball bearing of series 62 with suffixes 2RS1 and K is a single row bearing, sealed on both sides and with a tapered bore. It is used in applications requiring mounting on a tapered shaft and protection against contaminants. MR Accesorios Industriales supplies this line for different industries.
The designation 62..-2RS1K reads as follows: 62 indicates the medium section series, with larger outer diameter and width than series 60 for the same bore size. 2RS1 means it has contact elastomer seals on both sides, which retain lubrication and block dust and moisture. The final K indicates a tapered bore, generally 1:12 taper, for mounting on a shaft with an adapter or directly on a tapered shaft. Examples: 6206-2RS1K, 6207-2RS1K, 6208-2RS1K, 6209-2RS1K, 6210-2RS1K.
These bearings are used in equipment where the shaft is tapered and a firm fit without play is required: gearboxes, conveyors, machines for the food industry, packaging equipment, fans, pumps and agricultural machinery. In Argentina they are common in food and beverage plants, in the chemical industry and in applications with humid or dusty environments, where the 2RS1 seal prevents the entry of particles and grease loss.
To select correctly, take the load into account: deep groove ball bearings withstand moderate radial and axial loads. Series 62 accepts more load than 60 due to its larger section. The 2RS1 seal is already factory-lubricated and requires no maintenance, but it is not suitable for high speeds or extreme temperatures. The K taper requires precise mounting: use a lock nut and lock washer or adapter, and check radial clearance after tightening. Alignment between supports is key to avoid parasitic loads.
As for equivalences, each manufacturer has its own nomenclature. A bearing with the 2RS1 suffix from SKF may correspond to a 2RS, 2RSR or similar from another brand, but they are not always identical in seal material, internal clearance or tolerance. Series 62 with K tapered bore also exists in other brands with their own codes. It is always advisable to verify the main dimensions (bore, outer diameter, width) and seal type before interchanging. MR Accesorios Industriales can advise you if you send us the original code.

Frequently Asked Questions
- What are the dimensions of the SKF 6208-2RS1K bearing?
- The SKF 6208-2RS1K bearing has a 40 mm bore, a 80 mm outside diameter and a 18 mm width (40 x 80 x 18 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6208.
- What does the 2RS1 suffix mean on an SKF bearing?
- 2RS1 indicates that the bearing has contact elastomer seals on both sides. These seals retain grease and prevent the entry of dust, water or contaminants. It is a lifetime-lubricated configuration, ideal for dirty or humid environments.
- What is the K taper on the bore for?
- The K indicates a tapered bore, normally 1:12 taper. It allows the bearing to be mounted on a tapered shaft or with an adapter, achieving a controlled interference fit. It is used when a firm mounting and easy disassembly are required.
- Can I replace a 6206-2RS1K bearing with one from another brand?
- Yes, but verify that the main dimensions (bore, outer diameter, width), seal type and taper match. Nomenclatures vary between manufacturers. If you have doubts, consult us with the original code and we will help you find the equivalent.
