TONE RINGS OF WHEEL HUB ASSEMBLY
NUTEK ABS tone ring's materials are SS-410L, which is a kind of high quality stainless steel with good corrosion resistant, good magnetic inductivity and high magnetic strength. All the tone rings are machined with high preciseness to ensure proper spacing between the teeth and the sensor.
SPACING BETWEEN THE SENSOR AND THE TONE RING:
Must be <0.7mm; Maintaining the proper spacing between the sensor and the tone ring is crucial to keep good operation of the ABS.
SENSORS OF WHEEL HUB ASSEMBLY WITH ABS:
NUTEK has applied an integrated sensor with high quality especially for Generation 3 wheel hub assembly to eliminate leak paths into the bearing, thus improving durability and minimizing the potential handling damage.
n general, NUTEK cages are pressed steel ribbon cages & pressed steel snap cages for wheel bearing,
wheel hub assembly and A/C bearings, the cages are made from Nylon 66 with glass fiber.
SHIELDS & SEALS
NUTEK standard seals are made of oil and wear-resistant nitrile rubber(NBR) with a sheet steel reinforcement. SPCC is the standard material for shields we apply.
LUBRICATION
The grease can be applied upon customer's requirements. In general, Alvania R 2 is used for NUTEK small ball bearing. RONEX MP from ESSO Co. and ALVANIA R3 from SHELL are used for wheel hub bearings.Details as per our grease conversion table. |
