What is R+R
We understand R+R to mean the repair of used bearings and the modification / customisation / testing of standard bearings. The possibilities offered by state-of-the-art manufacturing processes are manifold.
Modifications / adjustments / tests:
- Adjustment of the internal clearance in C2/C3/C4/C5 (R801/R811/R821/R841/R851/R861)
- Production of conical bores from cylindrical bearings
- Turning of circumferential grooves (N / NR/ R802/ R812/ R822/ R842/ R852/ R862/ R892)
- Production of holding notches (N1/ N2 / R803 / R813/ R823/ R833/ R843/ R853/ R863/ R873) and combined grooves and notches (N3/ N4/ N5/ N6/ N3R/ N4R/ N5R/ N6R)
- Production of lubrication holes (S1 / W26 / R806 / R816 / R826 / R836 / R846/ R856/ R866/ R896)
- Production of lubrication channels, circumferential or spiral
- Pairing of tapered roller bearings (X/O/T / R834)
- Pairing of angular contact ball bearings (X/O/T/ R844/ R854 / R864 / R874)
- Pairing / matching of other bearings (R804/ R824)
- Measuring / testing / certification
- Check for cracks and inclusions
Repair:
It can make sense to recondition used types, especially for medium-sized and larger rolling bearings. Special bearings that are no longer manufactured are also frequently repaired.
Such repairs may include:
- Cleaning
- Inspection
- Grinding / polishing the raceways
- Replacement of cages / rolling elements
- Surveying
- Regreasing
Other service
- Customisation / production of conversion parts
- Customised packaging
- Ready-to-install product kits / pre-assembly
- Coating of housings
