Description
The bearing support rings measure 280 × 180 × 20 and 280 × 169 × 20 mm. The spacer rings come in sizes 130 × 150 × 8, 130 × 160 × 19.5, 220 × 250 × 8, 220 × 260 × 13, 220 × 272 × 30, 220 × 300 × 14, 240 × 270 × 10, 250 × 280 × 11 and 12, 360 × 400 × 15 mm. The guard rings are made 232 × 130 × 42, 240 × 130 × 28, 220 × 440 × 23 and 450 × 220 × 23 mm. For oil there are the oil-retaining ring PEAB 4435, a 488 × 540 × 15 mm ring for the PZAB 3541 and the oil splash deflector PEAB 4456,2. The bushings include a threaded M130 × 2 of grey cast iron EN-JL1040, 228 × 150 × 60 mm, the PEAB 4456 of 16MnCrS5 steel and a part with a 20H7 fit of EN-JS1030 cast iron. The end washers are 250 × 100 × 16.5 and 270 × 50 × 30.5 mm, and the holder is made of 580 × 390 × 12 mm plate of S355J2G3 steel. The parts fix the bearings axially, set clearances and keep oil from leaving the support. They are made to the original drawings, so fit dimensions and tolerances match the original design.
How to choose
Selection starts with the gearbox type and installation place. For the PEAB 4435 there is an oil-retaining ring, for the PEAB 4456 an oil splash deflector PEAB 4456,2 and a bushing of 16MnCrS5 steel, for the PZAB 3541 a 488 × 540 × 15 mm ring. Besides the type, specify the shaft (high-speed HSS or intermediate IMS) and the rotor or generator side. Order by the number of the gearbox manufacturer. Fasteners, oil fittings and seals for these gearboxes are separate items.

FAQ
Which gearboxes do these rings and bushings fit?
The PEAB 4435 (wind turbine V80/V90, 2 000 kW), PEAB 4456 (SWT-2.3, 2 300 kW) and PZAB 3541 (SWT-3.6, 3 600 kW).
What materials are the parts made of?
Steel C45+N, case-hardening 16MnCrS5, S355J2G3, grey cast iron EN-JL1040 and high-strength cast iron EN-JS1030.
Why are the rings replaced together with the bearing?
The fit surfaces wear or are damaged during removal, and axial fixing and clearances depend on the rings.
How should a part be ordered correctly?
By the manufacturer number, tied to the gearbox type and version and the installation place (HSS or IMS, rotor or generator side).
