SKF Motor Encoder Units with 2RS (Rubber Seal) are compact, ready-to-install assemblies designed to combine a precision bearing with an integrated speed-sensing encoder. These units are commonly used in electric motors, automation systems, and industrial machinery where accurate monitoring of shaft speed and position is required.

The unit integrates a deep-groove ball bearing, impulse ring, sensor body, and connecting cable into a single compact assembly. This design simplifies installation, reduces the number of components, and improves system reliability. The 2RS rubber seals on both sides protect the bearing from dust, dirt, and moisture while retaining lubricant inside, helping extend service life and reduce maintenance.

• Integrated bearing and encoder sensor in one compact unit

• 2RS double rubber seals for protection against contamination

• Pre-lubricated bearing for long service life and minimal maintenance

Adapter Sleeves

• Adapter Sleeves are components used to facilitate mounting of bearings with a tapered bore such as Taper Roller Bearings, Self-Aligning Ball Bearings, Spherical Roller Bearings, and Cylindrical Roller Bearings, on plain shafts or stepped shafts.
• On a smooth plain shaft, the bearing can be located at any position on the shaft.
• On a stepped shaft together with an L-shaped spacer ring, the bearing can be accurately positioned axially.
• It enables easy mounting and dismounting of Bearings

• Withdrawal Sleeves

  • Withdrawal sleeves can be used to mount bearings with a tapered bore onto the cylindrical seat of stepped shafts.
  • The sleeve is pressed into the bore of the bearing inner ring, which abuts a shaft shoulder or similar fixed component.
  • The sleeve is located on the shaft by a nut or an end plate. KM or HM lock nuts (Lock nuts requiring a keyway) with appropriate locking devices are suitable.

  Applications of Adapter Sleeves / Withdrawal Sleeves
  
  Adapter sleeves are mainly used in machinery, printing and dyeing, papermaking, chemical, aerospace, coal, petroleum, automotive, engineering machinery, steel industry, mining industry, cement industry, metallurgical and other industries.

• High load carrying capacity
  Double row tapered roller bearings are suitable for heavy radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e (from the product tables): the larger the value of e, the larger the contact angle.
• Axial loads in both directions
  Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload. 
• High stiffness
  Double row tapered roller bearings provide a stiff bearing arrangement.
• Low friction
  The optimized roller end design and surface finish on the flange ( fig. 3 ) promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.
• Long service life
  The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles of SKF Explorer bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends ( fig. 4 ), and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles ( fig. 5 ).
• Enhanced operational reliability
  Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
• Consistency of roller profiles and sizes
  The rollers incorporated in SKF double row tapered roller bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately.

Highly precise angular contact thrust ball bearings for precision we have been designed specifically for each application. Lineup includes both a highly rigid series and high-capacity series.
