SKF 2210 E-2RS1TN9 Sealed Self-Aligning Ball Bearing, 50 mm

Name: SKF 2210 E-2RS1TN9 Sealed Self-Aligning Bearing
Brand: SKF
SKU: 2210 E-2RS1TN9

Description

A sealed, greased-for-life self-aligning bearing that tolerates misaligned housings

The SKF 2210 E-2RS1TN9 is a double row self-aligning ball bearing with contact seals on both sides, a 50 mm bore, 90 mm outside diameter and 23 mm width. It has the same sphered outer-ring raceway as the open type, so it accepts static and dynamic misalignment of the shaft relative to the housing, but the integral sealing keeps the grease in and contaminants out. SKF cites reduced maintenance and longer service life from the integral sealing, plus low friction and good light-load performance.

Because the sealed bearing is greased at the factory and has no relubrication feature, it suits machines where bearings cannot be reached easily or where housing seals are minimal: conveyor idlers and rollers, agricultural and food-handling equipment, fans, and light line shafting. Its dynamic rating of 22.9 kN is lower than the open 1310 E of the same bore because the 22 series is a lighter section.

How to read the designation and what to confirm

2210 E-2RS1TN9 reads as follows: 22 is the self-aligning series, 10 is the 50 mm bore, E marks the higher-capacity internal design, 2RS1 is a contact seal on both sides and TN9 is the non-metallic cage. The 2RS1 seal limits speed compared with an open bearing, so the limiting speed is 4,800 r/min against a reference speed of 14,000 r/min, and the heat from seal friction should be considered in warm locations. Use the open 2210 E where you can lubricate from a housing and need higher speed.

Confirm the shaft fit and axial location: the cylindrical bore needs a shoulder and a nut or collar, while the tapered-bore equivalent 2210 E-2RS1K (with H 310 E sleeve in the catalogue table) fits a smooth shaft. Misalignment capability is a feature of the type, but it is not unlimited, so ask for the allowable angle for your series if the design relies on it.

About brand

SKF is the Swedish bearing manufacturer founded in Gothenburg in 1907. The company was built on the self-aligning ball bearing developed by engineer Sven Wingquist, who became its first managing director. Today SKF also makes seals, lubrication systems, condition monitoring equipment and maintenance tools.

Seven Star LLC is an independent supplier in Muscat. We list SKF bearings, greases, automatic lubricators, condition monitoring sensors and maintenance tools, and supply them to maintenance teams in Oman and the GCC by designation.

An SKF designation describes the bearing exactly. In 6205-2RSH/C3, "62" is a light-series deep groove ball bearing, "05" means a 25 mm bore (05 × 5), "2RSH" means rubber seals on both sides, and "C3" means internal clearance larger than normal, which motors often need because the inner ring runs warmer than the outer. Choosing the right grease matters just as much: a general grease such as LGMT 2 suits most motors, while heavy loads, high temperatures or slow speeds need an EP, high-temperature or high-viscosity grade.

Where SKF products are used

In Oman and the GCC, SKF bearings, lubricants and tools are used by maintenance teams in oil and gas, power and desalination, cement, mining, steel, water and food plants, and by motor and pump repair workshops.

Ordering SKF products: what we need

Send the full bearing designation including all suffixes (seals, clearance, cage), and the quantity. For greases, send the grade and pack size. For tools and lubricators, send the model and, for heaters, the largest bearing weight and bore you need to heat.
