Rotary R138 Shop 2D Low Speed Heavy Duty Wheel Balancer

Rotary R138 Shop 2D Wheel Balancer delivers precise tire balancing in under seven seconds without the noise of high-speed models. This low rotation speed balancer uses a heavy-duty 40mm shaft and a 10.5‑inch offset to securely handle deep‑dish and light truck tires up to 26 inches in diameter. Technicians rely on its integrated calipers to measure rim distance and width automatically, while the ALU S program and hidden weight program ensure accurate finishes on modern aluminum alloys.

Designed as a compact computerized balancer for professional shops, the unit employs Auto Stop On Top to halt spinning exactly at the external reference point whenever the protective hood closes. The bright red digital screen displays split readings with 1‑gram accuracy, and the standard 110V circuit requires no specialized electrical upgrades.

• Accepts 10–26 inch rims, 1.5–22 inch tire widths, and 143 pound maximum shaft weight
• Completes full balance cycles in 7 seconds at less than 100 RPM
• Automatically detects rim spacing and diameter via built‑in sliding calipers
