Inner oil seal collar is an mechanical component of oil seal, it plays an important role of fixing bearing . It is the core part of rolling bearing.The Oil seal collar works under low speed and heavy load for long time. It will drive parts need to be lubricated with the output parts isolation,so that the oil won't leak. Its reliability is the most important feature. To achieve this feature, it must in good quality .
1. Fine material, high level of wear resisting
Qingdao Zhengdao Heavy Industry Co., LTD uses high grade steel to produce the inner oil seal collar, to ensure products' quality. Through the test of practice, it can work well under long-time, heavy load operation with small wear loss.
2. Reasonable structure, good for long-time and stable operation
Removed outside top cover, this design avoids dusts go into bearing box, improves bearing's working life, and secures its work.
The fabrication route is governed by the provisions of the implemented Quality System ISO 9001: 2000. The standard documentation ensures the full traceability of every process step:
Manufacturer test certificates according to DIN EN 10.204 § 3.1 including chemical composition, mechanical properties and non-destructive examination;
Dimensional check supported with a "as-built" sketch;
Record of the heat treatment chart;
Oil seal is a mechanical component used to seal oil, it will drive parts need to be lubricated with the output parts iso, so that the oil will not leak.
