Products/Services for frictionless bearing

Featured Products
ROLLON Corporation
Compact Rail self aligning linear bearings

ROLLON Corporation's Compact Rail linear bearings are totally different from all the other linear bearing systems available in the marketplace. Most linear bearings are descendents of heavy machine tool bearings and therefore, by their very nature nature, tend to be slow, recirculating-ball carriages mounted on simple round or profiled shafts.

<B>Bearing</B> Retainers or <B>Bearing</B> Cages
Bearing Retainers or Bearing Cages - (12 companies)

Bearing retainers or bearing cages are used in rotary and linear bearings to separate and maintain a specified distance between rolling elements, whether they are balls, needle rollers, or rollers. Learn More about Bearing Retainers or Bearing Cages

<B>Bearing</B> Rings, Housings and Flanges
Bearing Rings, Housings and Flanges - (24 companies)

Bearing rings, housings and flanges are bearing components that are used in the assembly of many different types of bearings. Bearing rings, which are sometimes referred to as bearing races, guide a rolling element such as a ball, roller, or needle roller. Bearing housings and flanges hold an insert bearing in position, support the load transferred from the bearing shaft through the bearing, and are used to mount the bearing to a surface.

Ball <B>Bearings</B>
Ball Bearings - (479 companies)

Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings types include radial ball bearings (deep groove and angular contact) and thrust ball bearings. Search by Specification | Learn More about Ball Bearings

Angular Contact <B>Bearings</B>
Angular Contact Bearings - (206 companies)

Angular contact bearings are designed so that a contact angle between the races and the balls is formed when the bearing is in use. Search by Specification | Learn More about Angular Contact Bearings

Super Precision and Spindle <B>Bearings</B>
Super Precision and Spindle Bearings - (73 companies)

Super precision and spindle bearings are high-precision bearings that are designed for use in machine-tool spindles and other precision applications. Most super precision bearings and spindle bearings carry a high quality-rating such as ABEC-7 or ABEC-9, and run coolly and smoothly at high speeds.

Miniature <B>Bearings</B> and Instrument <B>Bearings</B>
Miniature Bearings and Instrument Bearings - (135 companies)

Miniature bearings and instrument bearings carry moderate radial and thrust loads at low operating torque while providing high performance in a small envelope design. These types of bearings are single row ball bearings available in up to 1 1/8" outer diameter (OD) sizes Search by Specification | Learn More about Miniature Bearings and Instrument Bearings

Roller <B>Bearings</B>
Roller Bearings - (319 companies)

Roller bearings are used in rotary applications to replace sliding movement with low friction, rolling motion. The principal types of roller bearings are cylindrical, spherical, and tapered. Search by Specification | Learn More about Roller Bearings

<B>Bearing</B> Isolators
Bearing Isolators - (45 companies)

Bearing isolators are dynamic seals designed to protect bearings from outside contaminants. They are comprised of a rotor (rotating) and stator (stationary) member. Search by Specification | Learn More about Bearing Isolators

Plain <B>Bearings</B> and Sleeve <B>Bearings</B>
Plain Bearings and Sleeve Bearings - (379 companies)

Plain bearings and sleeve bearings (also referred to as bushings or journal bearings) are used to constrain, guide or reduce friction in rotary or linear applications. They function via a sliding action. Search by Specification | Learn More about Plain Bearings and Sleeve Bearings

Flange Mounted <B>Bearings</B>
Flange Mounted Bearings - (201 companies)

Flange mounted bearings are used when a shaft axis is perpendicular to the bearing mounting surface. They are available in 2, 3, or 4-hole configurations. Search by Specification | Learn More about Flange Mounted Bearings

Takeup <B>Bearings</B>
Takeup Bearings - (97 companies)

Take-up bearings are primarily used to correctly tension conveyor belts and systems, or to align tracks. They are available in three component types: bearing, frame, and take-up assembly (frame with bearing). Search by Specification | Learn More about Takeup Bearings

Tapered Roller <B>Bearings</B>
Tapered Roller Bearings - (213 companies)

Tapered roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers, which are profiled to distribute the load evenly across the roller. Search by Specification | Learn More about Tapered Roller Bearings
