FAQS

QWhat is Needle Roller Bearings?

Aoperating temperature, internal clearance for therm al expansion, and whether the bearing has seals or shields Bearings Direct supplies a large variety of roller bearings and needle roller bearings. Roller be arings are any cylindrical or spherical object that aids in the movement of an object greater i n size than the bearing itself. A roller bearing is a weight distribution-oriented bearing.

QWhat is Radial deep groove bearings?

AMiniature, Deep-groove bearings however do have higher load ratings for their size than shallow-groove ball bearings, but are also less tolerant of misalignment.

QWhat is Shields & End Covers Bearing Isolators?

AClosed bearing covers completely  encase the bearing, while open covers have an exposed center to allow access to the bearing.  Closed and open bearing covers are typically made of plastic with metal fasteners. Bearing isolator seals: Bearing isolators combine the characteristics of contact and non- contact seals in a single unit (Fig. 3), but use the contact features to “drive” part of the seal at the shaft’s rotating speed.  Such seals afford more protection than individual contact or non-contact seals.
