FAFNIR SUPERPRECISION BEARINGS

2MMV - HX type, with 15initial contact angle is designed to meet the needs of machine manufacturers who require optimum oil flow through the bearings. This design incorpo- rates a low shoulder on the non-thrust side of both the inner and outer rings. The maximum complement of balls is separated by a one-piece cage which pilots against the ground land of the outer ring.

Fafnir has developed an ISO Series – 10 bearing designed to enhance two key factors contributing to metalworking throughput: spindle speed and radial stiffness.

2MMV-HX Type

This design enables spindle heads to remove more material in less time while maintaining superior finished product tolerances by minimizing tool “wander”. This efficient combination translates into faster turn around of finished product. These improvements are imparted by subtle changes to ball complements and internal geometries concluded by Fafnir design engineers as being a reliable path toward better machining efficiencies.

The Fafnir HX Series is dimensionally interchangeable with our present 9100 and 99100 series spindle bearings along with competitive ISO Series-10 designs.

Ballscrew Support Bearings

To meet the requirements of the servo-controlled machinery field, Torrington has developed a new series of ball bearings specially designed for ballscrew applications. Design criteria for these bearings are maximum axial rigidity, low drag torque, and extreme control of lateral eccentricity.

These bearings are manufactured to ABEC-7 tolerances and are of the nonseparable angular-contact type design with a 60contact angle and maximum complement of balls.These bearings are supplied prelubricated with heavy duty grease NLGI #2 . Bearings are supplied packaged in DB arrange- ment. However, they can be mounted in duplexed pairs and in multiplexed sets in either Back-to-Back (DB), Face-to-Face (DF) or Tandem (DT) arrangements.

Standard sizes are available and are stocked and pack- aged as duplex pairs, triplex sets or quadruplex sets. These bearings are designed primarily for ballscrew applications and should not be considered in other areas such as spindles or gear-box shafting without approval by our Engineering Department. These bearings are offered in both standard inch and metric envelope dimensions.
