Ball Lock¬Æ Liners, part number 49856, are designed for use in applications requiring precise locating and repeatability. Made from 52100 steel with a black oxide finish, these liners are heat-treated to a hardness of 62-64 RC, ensuring durability and strength. They operate effectively within a temperature range of -20¬8F to 400¬8F (-30¬8C to 200¬8C). The installation guidelines specify that to prevent binding, the maximum interference fit between the bore and bushing outer diameter should not exceed 0.0005" (0.013mm). The product is suitable for applications where maintaining tight tolerances is critical, particularly in workholding setups.
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.
