Adaptador Simucube 50,8mm para 70mm para wheelbases — Simucube SC50870A

The Simucube 50.8mm to 70mm adapter (SC50870A) is a mechanical mounting adapter that converts a 50.8 mm bolt pattern to a 70 mm bolt pattern for compatible force feedback wheelbases and steering rims. Designed to maintain correct alignment between the wheel hub and rim, this adapter allows users to mount rims or quick releases with different mounting standards while retaining a secure connection and accurate torque transmission.

Advantages

This adapter provides a precise mechanical interface between two common bolt patterns, reducing play and preserving steering accuracy. Its construction ensures a stable connection under load from force feedback systems and helps maintain concentricity between the wheelbase hub and the rim. The adapter simplifies compatibility issues between older and newer rim standards, allowing users to switch rims without modifying the wheelbase or the rim.

Suitable for

• Converting a 50.8 mm bolt pattern on a Simucube-compatible wheelbase to a 70 mm rim or quick release
• Users who want to fit rims with a different mounting standard without replacing the wheelbase
• Sim racing setups requiring precise mechanical alignment between hub and rim

Key specifications

• Input bolt circle diameter: 50.8 mm
• Output bolt circle diameter: 70 mm
• Function: mechanical adapter for converting bolt patterns
• Purpose: secure attachment between wheelbase hub and steering rim or quick release
• Compatibility: designed for use with Simucube-compatible wheel hubs and rims using the specified bolt patterns

How to use

Mount the adapter so that the 50.8 mm side aligns with the wheelbase hub and the 70 mm side aligns with the rim or quick release. Use the appropriate bolts and torque values recommended by the wheelbase and rim manufacturers to fasten the adapter securely. Verify concentric alignment and check that all fasteners are tightened evenly to prevent wobble and ensure reliable force feedback transfer during use.

Recommendations

Inspect mounting surfaces for debris or damage before installation, use thread locker where recommended by the manufacturer, and follow the wheelbase and rim torque specifications. Periodically recheck fastener tightness after initial use to maintain secure mounting and consistent feedback performance.
