The design knowledge of the deep ditch ball bearing of stainless steel:

First, take the bearing of the sealed circle:

Suffix seal, enclose, have the intersection of steel and skeleton resist oil and resist for 2RS1 abrade make the nitrile rubber to make. This thanks sealed circle for sealed circle’s working temperature of permission – 40 takes contact-typely to seal the bearing of the circle to 100 ℃. Short time can reach 120 ℃ high. The contact-type sealed lip which seals the circle is sealing the shoulder in the inner circle. Seal and enclose the outer fringe in the groove of the outer lane, this position can offer the good sealed result.

Such as the extremely high rotational speed or high temperature, when the sealed bearing runs under some extreme conditions. May cause lubricating grease on the inner circle and seal the leakage during enclosing. Reveal situation, can dispose, lead to the fact damage nature influence to bearing, must pass the special design method.

,The car bearing trade leads in websites, the subordinate characteristic column: The intersection of bearing and the intersection of type and inquiry, the intersection of bearing and type inquire software, bearing navigate etc., looks forward to your concern, please continue reading:

Second, take the bearing of the dustproof lid:

The suffix is made of stainless steel for 2Z dustproof lid. Build the intersection of jade and shoulder of inner circle, form an extremely narrow interval while being dustproof, take the dustproof bearing that builds. And can bear high temperature and high rotational speed. Take the dustproof bearing that overlays to be mainly applied to the operating mode that the inner circle rotates. If the outer lane rotates, the bearing will cause lubricating grease to let out under operating at a high speed.
