Carbon steel · ID/OD sealing grooves · Ra32 µin fine finish
Multiple ID/OD sealing grooves turned; sealing faces at Ra32µin for reliable seal seating
| Part Type | Rod seal gland (for machine tools) |
| Material | Carbon steel 1018 |
| Accuracy | ID/OD ±0.002 in (±0.05mm), concentricity 0.001 in |
| Surface Finish | Sealing faces Ra 32 µin (~Ra 0.8 µm) |
| Process | CNC turning (multiple ID/OD seal grooves) + drilling |
| Treatment | Rust-inhibiting oil |
| Application | US machine-tool OEM · horizontal machining centers |
Multiple sealing grooves on both bore and outer diameter are CNC-turned; groove form and position directly affect seal seating and sealing performance.
Sealing faces require Ra32µin (~0.8µm); finish turning balances surface quality and dimension to ensure dynamic seal life.
Concentricity between bore, OD and datum is held to 0.001in, maintaining uniform clearance for the rotary seal.
