Ball Lock¬Æ Liners, part number 49755, are designed for use in workholding applications that require precise locating and repeatability. Made from 52100 steel, these liners feature a black oxide finish and are heat-treated to a hardness of 62-64 Rockwell C. They can operate effectively within a temperature range of -20¬8F to 400¬8F (-30¬8C to 200¬8C). The installation of these press-fit liners requires careful attention to the interference fit, which should not exceed 0.0005" (0.013mm) to prevent binding. For applications needing high repeatability, using two primary liners can maintain a tolerance of ¬±0.0005" (¬±0.003mm) when the holes for receiver bushings are aligned within ¬±0.0002" (¬±0.005mm). These specifications make the Ball Lock¬Æ Liners suitable for engineers seeking reliable and efficient workholding solutions.
Locating repeatability will determine if (1) primary and (1) secondary or (2) primary liners are needed. With (2) primary liners, repeatability of ±0.0005" (±0.003mm) can be maintained if the (2) holes for receiver bushings are held to a centerline distance of ±0.0002" (±0.005mm) tolerance.
Features, Benefits, & Product Specifications:
On Installation of Press Fit Liners & Back Mount Style Receiver Bushings:
To alleviate the possibility of binding the shank in the bore, the maximum interference fit between bore and bushing O.D. should not exceed 0.0005" (0.013mm).
