Regulating Wheel Size (OD × WD × ID)
Regulating Wheel Size (OD × WD × ID)
Introduction
The regulating (control) wheel defines workpiece rotation, feed rate, and stability in centerless grinding. Selecting the correct OD × WD × ID ensures roundness, surface finish, and throughput. Below is a concise guide to typical sizes, selection rules, and application notes for automotive, bearing, and precision engineering components.
Description
A regulating wheel is a rubber or resin-bonded wheel that drives and supports the workpiece against the grinding wheel. Wheel size is denoted as Outside Diameter (OD) × Width (WD) × Bore/Inside Diameter (ID). Larger ODs improve thermal stability and life; wider widths support longer or heavier parts; the ID must match the machine spindle. Compound and hardness are chosen alongside size to suit material, stock removal, and finish requirements.
Typical Regulating Wheel Sizes (OD × WD × ID)
| OD (mm) | WD (mm) | ID / Bore (mm) | Typical Use | Notes |
|---|---|---|---|---|
| 250 | 100 | 127 | Small pins, dowels, needle rollers | Compact footprint; light-duty applications |
| 300 | 125 / 150 | 127 / 152.4 | Shafts up to ~25 mm, bush parts | Balanced choice for job shops |
| 350 | 160 / 200 | 152.4 / 203.2 | Automotive valves, transmission rollers | Improved thermal stability |
| 400 | 200 / 250 | 203.2 / 228.6 | Crank pins, steering shafts | Good for medium-heavy parts |
| 450 | 250 / 300 | 228.6 | Long bars, bearing races | Wider face supports longer parts |
| 500 | 250 / 300 | 228.6 / 304.8 | Heavy shafts, tube stock | Extended life; higher mass damping |
| Custom | Up to 350 | As per spindle | Special fixtures, automation lines | Profiles / crowns available on request |
Selection Guidelines
- Part Size & Weight: Increase OD/WD for longer, heavier, or less rigid parts to control chatter and taper.
- Surface Finish: Larger OD and correct crown/profile improve line contact and finish consistency.
- Feed & Throughput: Choose width to maintain contact area at target feed angle and rate.
- Bore Matching: ID must match machine spindle (with proper bushings if specified by OEM).
- Compound & Hardness: Softer wheels grip better for small/light parts; harder wheels suit heavier feeds.
Where These Sizes Are Used
- Automotive: Pins, rocker shafts, valve stems, pump rotors requiring tight roundness and Ra finish.
- Bearings & Powertrain: Rollers, races, and transmission components with controlled feed angles.
- General Engineering: Bars and rods for hydraulic, tooling, and fabrication industries.
