Flexbar Ball Bearing V-Blocks

BALL BEARING “V” BLOCK

Overcomes Production or Set-Up Difficulties Inherent in Plain V-Blocks. Overcomes Geometric Limitations.

Enables you to inspect and detect out-of-round conditions and lobes with no damage to parts and no damage to blocks.

SPECIAL FEATURES:

• Accuracy of Balls: 25 millionth of an inch sphericity on small and medium set. 50 millionths of an inch on large set.
• Overall accuracy of matched pairs +/-5 microns
• Balls Rockwell C-62 – Surface finish 0.2 microinches
• Calibrated balls are certified
• Class 40 cast iron, used on base and housing, is heat stabilized and seasoned
• Spacers are hardened through and precision ground by pairs
• Pair of blocks assembled using metrology equipment

AVAILABLE IN 3 SIZES WITH RANGES OF: 3/64″-2 1/2″; 3/22″-5″; 3/16″-15″ AND UP.
SOLD IN MATCHED PAIRS COMPLETE WITH CLAMPS (for use when machining).

SPECIAL FUNCTIONS:

• Balls undergo slight elastic deformation when parts are loaded on. Hence parts will not be damaged while being inspected or produced.
• Detection of lobes and superimposed lobes made easy
• Easy readjustment of balls which provide new bearing points
• Handles diameters up to 15 inches
• Increased contact area due to special geometric spacing of balls in blocks
• 8 contact points per pair of blocks share load distribution
• Balls are self-aligning and hard wearing
• 1 each precision spacer per block provides 2 different angles per pair
• Simply turn each block 90 and inspect component using both angles
• Special inspection set ups using cylinder squares now possible

IMPORTANT NOTE: Balls are fixed in blocks and are not designed to rotate in use.
