utilize the same compact body design.
• Aluminum body, hard anodized externally
and internally, for corrosion and wear
resistance.
• Electrostatic powder coating (ESPC)
finish, external on body, internal and
external on end caps, protects against
corrosive environments.
• Adjustable travel stops.
• Safe end cover bolting requiring no
special tools.
• Anti-blowout drive pinion.
• Over travel adjustment (at each end) +5°.
• Under travel adjustment (at each end) -10°.
• Easy field conversion between DA and
SR models.
