R in inch-sizes Series Deep Groove Ball Bearings
Product benefits of TFL Bearing’s R in inch-sizes Series Ball Bearing:
- light series with compact dimensions and low weight
- suitable for high radial loads and light axial loads in both directions
- suitable for high running accuracy, quiet running, and high speeds
- seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
- the good fixed bearing property, but can also be used as a floating bearing, each in both directions
- manufacturers of bearings, such as FAG, KOYO, NSK, SKF, SNR, OEM, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)

Special feature of this series
Ball bearings of this light series in Zoll/inch-dimensions still support moderate radial loads despite their low weight. In comparison to deep groove ball bearings of the RMS series, they require a smaller installation space at the same inside diameter, only weigh approximately a third of them and allow higher speeds furthermore.
Rubber seals (RS/2RS) have the optimum sealing action with increased friction. Metal seals (Z/ZZ) are suitable for higher speeds, but they have a limited sealing action as they seal contactless. Open, seal-less bearings are suitable for extremely high speeds and – furthermore – they can be regreased more easily. However, they are more susceptible to soiling.
Manufacturers of bearings: such as FAG, KOYO, NSK, SKF, SNR, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)
Can be customized to meet your specific needs.
Lightweight, stable, and with good spinning characteristics. The deep groove ball bearing R8-W6.35 in inch-size is a true all-rounder and, due to its balanced properties, it is suitable for a variety of applications.
Other options: Metal shield (ZZ) or rubber seal (2RS) can be provided.
Deep Groove Ball Bearings are able to accommodate low to heavy radial loads and low to moderate thrust loads in either direction. They are available with metal shields (ZZ) or rubber seals (2RS). Several tolerance grades (Abec 1-9), internal clearance (C2 to C4) and cage designs are available to best suit the running precision and speed of the application.
- ZZ– Two Metal Shields
- 2RS– Two Rubber Seals
- NR– Snap Ring
- M– Brass Cage
- C0– Normal Internal Clearance
- C3– Greater than normal
