Rolling Bridge Jack RJ6100Y-1 — OEM 6,000 lb Jack for Older Rotary® 4-Post Lifts
The Rolling Bridge Jack RJ6100Y-1 is the official 6,000-lb air/hydraulic bridge jack engineered for pre-April 2000 Rotary 4-post lifts with welded runways. If your shop relies on legacy Rotary equipment, this is the correct OEM solution for wheels-free lifting, brake service, tire work, and suspension repairs—without moving the vehicle or tying up your 2-post bays.
Designed for professional service centers, performance shops, fleet facilities, and high-volume repair operations, the Rotary Rolling Bridge Jack RJ6100Y-1 delivers the durability, safety, and precision Rotary is known for.
Key Benefits (Built for Shop Productivity)
Shop owners and service managers choose the Rolling Bridge Jack RJ6100Y-1 because it:
- Enables wheels-free lifting for brakes, tires, suspension, and alignment work
- Increases revenue per bay by allowing more services on your 4-post lift
- Improves workflow efficiency—no repositioning vehicles
- Extends the life of older Rotary lifts without costly replacement
- Provides smooth, controlled lifting with air/hydraulic power
- Reduces technician fatigue with easy-glide wheels and debris sweeper design
- Fits correctly and safely on older welded-runway Rotary lifts
This aligns with proven purchasing behavior: shop managers overwhelmingly prefer OEM Rotary equipment for reliability, safety, and long-term value.
What the Rolling Bridge Jack RJ6100Y-1 Is Designed For
This jack is ideal for shops that regularly perform:
- Brake jobs
- Tire rotations and wheel swaps
- Suspension diagnostics and repairs
- Alignment preparation
- Undercarriage inspections
It turns your 4-post lift into a complete service station, expanding your shop’s capabilities without adding new construction, electrical work, or additional lifts.
Compatibility (Critical for Older Rotary Models)
The RJ6100Y-1 is specifically engineered for:
Rotary 4-post lifts with welded tracks manufactured before April 2000, including:
- SM121
- SM122 / SMO122
- AR122 / ARO122
- Other equivalent pre-2000 welded-runway Rotary models
If your lift features welded, not bolt-on runways, this is the correct OEM bridge jack.
Why Technicians Prefer the RJ6100Y-1
Technicians consistently highlight:
- Stable load handling
- Quick operation with air/hydraulic actuation
- Easy travel across the lift with smooth glide wheels
- Clean working environment thanks to the built-in sweeper
- Consistent lifting points due to Rotary’s included adapters
These quality-of-use improvements translate into higher output and safer operations every day.
