Ball Lock¬Æ Liners, part number 49758, are designed for use in workholding applications where precise locating and repeatability are critical. Made from 52100 steel with a black oxide finish, these liners are heat-treated to a hardness of 62-64 Rockwell C, ensuring durability and resistance to wear. They operate effectively within a temperature range of -20¬8F to 400¬8F (-30¬8C to 200¬8C). The installation of these liners requires careful attention to the fit; the maximum interference fit between the bore and bushing outer diameter should not exceed 0.0005" (0.013mm) to prevent binding. The product is suitable for applications that demand high precision, with the potential to maintain a repeatability of ¬±0.0005" (¬±0.003mm) when installed correctly.
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.

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).
