Ball Bearings（Size Standards：Inch Series）

Technical Information【BALL BEARINGS】
Ball bearings are used to reduce friction of a rotary shaft mounted on the machine. Reducing friction helps increase the machine efficiency, extend lifespan and prevent seizing and failure. Ball bearings consist of balls (rolling elements), the inner ring, the outer ring, the cage (for keeping the balls in appropriate motion), and are used for many machines requiring rotary shafts, such as motors equipped in electric tools, etc. Types of ball bearings are as follows; angular bearings which support radial and axial loads by combination of single row and double row, thrust bearings which support forces acting in the axial direction of a rotating object, and self-aligning bearings used when the inner and outer rings of a bearing are tilted. In addition to materials, sizes, basic load ratings, and allowable rotational speeds, there are a wide variety of types of shields, greases, outer ring types, etc., requiring you to select a suitable ball bearing for the application.

Thrust Ball Bearing - Inch, 600 Series

NICE BEARINGS

The 600 Series bearing is designed for moderate speeds and medium thrust loads. These bearings utilize a full ball complement. Rings are cold forged from hardenable strip steel and are carefully heat treated. These bearings may be plated or manufactured from stainless steel upon request.

The entire assembly is housed in a soft steel band which lends itself to an easy press fit into a housing. The band also serves as a dust shield and helps retain the bearing lubricant. The upper ring is free to rotate in the band and has a close fit in the bore for the shaft. The lower ring is fixed in the band and has a shaft clearance in the bore.

Features:

• Unground Thrust Bearing

• Easy To Use Inch Dimensions

• Moderate Loads

• Max Speed Range: 1000 - 1200 RPM

• Hardened Rings

• Full Complement of Balls

• Soft Steel Band Offers Ease of Installation

• Upper Ring is Free to Rotate and has Close Fit for Shafts

• Lower Ring is Fixed and has Shaft Clearance in the Bore

Thin Section Four-Point Contact Ball Bearing

RBC BEARINGS

The X-Type, or 4-point contact, ball bearing is ideal for moment loading. X-Type bearings are designed with gothic arch raceways creating 4 contact points between the balls and the raceways. This design is excellent for moment loading and reversing axial loading. The X-Type bearing can be used for other light loading conditions, but is not recommended in place of the C- or A-Type bearing for pure radial loads.

Thin Section Angular Contact Ball Bearing

RBC BEARINGS

In applications with high axial loads the A-Type, angular contact ball bearing should be used. This bearing also works well in radial or combined radial-thrust applications. The A-Type bearing should never be used alone to support moment loads or reversing axial loading.

Deep Groove Ball Bearing - Single Row, Inch, 3000 Series

NICE BEARINGS

Semi-ground 3000 Series bearings are specially designed to provide a line of economical bearings for lighter loads than the 1600 Series bearings and speeds to approximately 2500 rpm. The 3000 Series bearings are dimensionally the same as the 1600 Series bearings, except for the precision of the inner ring.

The 3000 Series radial bearing is available open, single or doubled shielded, or single or double sealed. The double shielded and double sealed versions are grease packed as standard. Open and single closure bearings can be furnished with or without grease as desired.

Insert Ball Bearing - Single Row, Inch, 7600 Series

NICE BEARINGS

The 7600 Series bearings are single row retainer type radial bearings similar in construction to the 1600 Series bearings. They incorporate a highly efficient single lip contact seal with metal guard. The inner and outer rings are turned from chrome steel and after careful heat treatment the through hardened rings are accurately ground to close tolerances.The inner ring is extended and contains set screws whereas the 7500 Series bearing does not.

The 7600 Series bearings are recommended for applications requiring the accuracy of rotation and quiet performance of close limit precision grade bearings, and where a superior seal is required to retain lubricant and keep the bearing free from dust and dirt.

Normally double sealed (type DL), the 7600 Series bearings can be produced to order with seals on one side only (type SL) or without seals (type NL). Double sealed bearings are grease packed as standard; however, all types can be furnished with or without grease packing as desired. All types are provided with a snap ring groove, with the snap ring assembled on the bearing as an option.
