Product overview
The Cablecraft KRF1600 Ball Bearing Control Cable is a heavy-duty, high-efficiency push-pull control cable engineered for precise motion transfer, low lost motion, and reliable performance in demanding aerospace and industrial environments. Recommended load capability is up to 500 lbs. (normal duty) and 1,000 lbs. (limited duty). The KRF1600 is commonly evaluated as a replacement for AeroControlex-style ball bearing control cables when fit, function, stroke, routing, and end fittings are confirmed.

Key Benefits

• High load capability: recommended 500 lbs. normal duty; 1,000 lbs. limited duty
• High-efficiency motion transfer: 90%–98%
• Low lost motion for accurate, repeatable control
• Dry-running design — no lubrication required
• Wide operating temperature ranges (depends on vinyl covering or bare construction)
• CRES stainless steel construction for corrosion resistance
• Optional vinyl covering for added protection
• Custom-built to specification for length, stroke, routing, and fittings

Common Applications

• Aircraft flight controls
• Helicopter flight controls
• Engine controls
• Marine systems
• Industrial control systems
• Heavy-duty mechanical actuation systems
• Long-routing push-pull control applications
• Replacement cable applications where part cost or lead time are considerations

Important design notes
Rated compression loads are limited to a 4-inch maximum stroke. Normal duty assumes a minimum product life of 100,000 cycles. Before selecting as a replacement, confirm existing part number, overall cable length, stroke length, normal and limited load requirements, end fittings and terminals, thread sizes, bend radius, cable routing, environmental exposure, temperature range, compliance or testing requirements, mounting requirements, and quantity/lead time needs.
