Worm drives

Material:
Housing aluminium.
Worm screw steel, worm wheel special brass.

Version:
Housing anodized.
Worm screw case hardened.
Ball bearing with rubber sealing washer RS.

Note:
Universally applicable and maintenance-free worm drive in one size with a centre distance of 20 mm and 7 different ratios. The housing is sealed to prevent grease leakage and keep dust out. These are left hand worm gears. The rotation direction on the shaft is arbitrary.

- smooth power transmission
- simple screw fastening
- quiet
