End Cap Design
The end-cap type ball recirculation system allows the nut length to be reduced and minimizes the outer diameter. No return mechanism protrudes outside the nut body diameter. Double flats on the flange make the unit ideal for use in small spaces.
Return Plate Design
This design provides ball recirculation for low lead screws without return tubes protruding from the nut body. Coil type deflectors are used to divert the balls into the return system. Overall size is minimized and the flange has double flats as on type A.
