Ball Lock¬Æ Liners, part number 49842, are designed for use in workholding applications requiring high precision 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 product allows for a repeatability of ¬±0.0005" when using two primary liners, provided that the holes for receiver bushings maintain a centerline distance tolerance of ¬±0.0002". Installation guidelines specify that the maximum interference fit between the bore and bushing outer diameter should not exceed 0.0005" to prevent binding. These specifications make the Ball Lock¬Æ Liners suitable for applications requiring precise alignment and secure mounting in various machining environments.
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).
