The FAG 22..-2RS-TVH series covers self-aligning ball bearings that use two rows of balls running on a spherical raceway in the outer ring. That arrangement lets the bearing absorb angular misalignment between shaft and housing, including while the machine is running. Both sides carry elastomer seals, and the rolling elements are held by a polyamide cage. Typical installations include fans, pumps, conveyors and agricultural equipment where alignment is imperfect or the shaft flexes.
Reading the code helps you order the right item. The basic number gives the size, while the letter groups describe the design. The leading 22 belongs to the reduced outside diameter series. The 2RS marking tells you that elastomer seals sit on each side, keeping lubricant in and contaminants out. TVH identifies the glass fiber reinforced polyamide cage, which matches the speeds usual for this series. Knowing these suffixes avoids mistakes when the part number is written from memory.
These bearings fit centrifugal and axial fans, centrifugal pumps, belt conveyors, mixers, screens and farm machinery, as well as textile machines, bottling lines and air treatment units. Their self-aligning behavior is an advantage on long shafts that flex or where the support cannot be aligned precisely. MR Industrial Accessories LLC supplies this FAG line for replacement work and new projects to customers throughout the United States and in several Latin American countries.
Selection depends on radial and axial load, rotation speed and the surrounding environment. The 22 series handles moderate radial loads and a certain amount of axial load in either direction. The 2RS sealing suits dusty or moderately humid conditions; where water or fine particles are present, consider heavier sealing or a protected housing. During mounting, check the initial alignment and do not strike the rings. The factory fill of lubricant covers most applications, though severe conditions may call for periodic relubrication.
Other brands offer self-aligning bearings with comparable designations: the 22.. series plus suffixes for sealing and cage type. SKF, NSK, NTN and SNR equivalents are common in the market. Dimensional interchange is generally direct, but confirm the seal and cage styles, since they affect performance. If anything is unclear, send us the original part number and we will help you choose.

Frequently asked questions
- FAG 2311-2RS-TVH bearing: what are its dimensions?
- FAG 2311-2RS-TVH measures 55 mm across the bore and 120 mm across the outside diameter; its width is 43 mm (55 x 120 x 43 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2311.
- What does the 2RS suffix mean on these bearings?
- It shows that elastomer seals are fitted on both sides. These seals keep the lubricant inside and block dust and humidity, which helps in contaminated environments.
- Are they interchangeable with bearings from other brands?
- In most cases they interchange dimensionally with equivalent series from other makers. Check that the seal type and cage suit your application. If in doubt, send us the original part number.
- How do I request a quote for these bearings?
- Send the complete bearing part number or the shaft and housing dimensions on WhatsApp. We reply promptly with the quote.
