FAQS

QWhat is Shields & End Covers Bearing Isolators?

A Closed 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.

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 Needle Roller Bearings?

ANeedle roller bearings are used with radial loads only, and their selection is typically based o n the amount of the load, whether an inner ring is required, the material that the rollers, ri ngs, and cage are made from, rotational speed, operating 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 Flange-Mount Ball Bearing?

AThe flange may be the machined or cast protruding lip of a bushing, or it may be a type of bearing housing with bolt holes in the casting to accommodate mounting. A flanged ball bearing is not truly a different type of bearing. Just as ball bearings are o ffered sealed or open, they are also available flanged or plain. The flange is just another opt ion given to the design engineer by the bearing manufacturer.
