WD BEARINGS FOR INDUSTRIAL PLANETARY GEARBOXES

2025-05-09

Summary

Modern industrial planetary gearboxes are now being developed with a trend toward a smaller envelope but with an increased power level. This places high requirements on the rolling bearings being used. WD provides full-complement Cylindrical Roller Bearings of higher quality for high-power-level gearboxes. This type of bearing features heavy loading capacity, long lifespan, high reliability, low friction and noise during operation, a compact structure, and a simple installation process.

Bearing Structure

For a high load carrying capacity, the bearings are full complement designed and can be divided into "single row" and "double row" according to the rolling elements. According to installation requirements, the snap rings can be located between or by the sides of the two rows of rollers. Mating snap rings and spacers can be provided.

A plastic protection ring is used for bearings without outer rings so that the installation is simple for the customer, as well as protects the bearing from damage during transportation.

Bearing Capacities

Logarithmic curved rollers are used to increase the load carrying capacity and lifetime. There are two high-strength ribs in the inner ring, so the bearing can afford some axial loading and realise axially bidirectional guidance through the snap ring and spacer. In assembly, the mating shaft should be done with a high-enough abutment shoulder, which is perpendicular to the bearing axes, to avoid bearing axial creep.

No pre-lubrication is applied for the bearings, so either oil or grease can be applied during usage in accordance as requested.

Special surface treatment, such as phosphating or black oxide, is available to improve the run-in capability, which makes these bearings particularly suitable for slippery applications.

For working conditions that involve continuous use, the minimum radial load applied should conform to Cor/P < 60. The limiting speed must not be exceeded even under favourable operating and cooling conditions.

Bearing Fit Design

Fit

The inner ring is interference fitted with the shaft due to the circumferentia load on the inner ring.

Raceways

In rolling bearings without outer rings, the mating gear inner diameter is used as an outer raceway. The raceway must be hardened and precision machined. The axial washer and abutment shoulders should also be precision machined and resistant to wear.

Through-hardening steels such as 100Cr6/GCr15 and case-hardening steels such as 16MnCr5, 16NiMo6/20CrMnTi, and 20CrMo are suitable as materials.

The raceway hardness must be harder than HRC58 (HV650); otherwise, the load-carrying capacity will decrease. The basic dynamic loading, Cor, and static loading, Cr, can be adjusted by reducing the hardness factor (for details, please contact WD engineers).

The wall thickness between the raceway and tooth base should be at least 2.5 times the modulus.

The raceway must be ground. For roundness, parallelism, and roughness (Ra), refer to the table below. The load-carrying capacity will decrease if Ra is out of tolerance.

Bearing Accuracy and Clearance

Accuracy

The dimensional and running tolerances of the bearingscorrespond to tolerance class PN to DIN 620.

Bearing ID d mm		Envelope circle diameter Ew mm
Tolerance of envelope circle diameter Ew	over	incl.	Upper	Lower
		40	0	-0.010
	40	65	0	-0.015
	65	120	0	-0.020
	120	200	0	-0.025
	200	250	0	-0.030

Radial internal clearance

For the bearings without an outer ring, the planetary gear fulfils the function of the outer raceway. So the bore of the planetary gearbox is determined by the combination of the selected radial clearance (C2, CO, C3, C4) and the envelope circle diameter, Ew.

e.g: For RNN50V-9, the bearing Ew is -0.015mm. If the selected clearance is CO (30-60μm), then the bore tolerance of the planetary gearbox is (+30/+45μm).
