Kollmorgen S61400-PB
Product Series: S61400 (Encoder Housing & Accessories)
Product Introduction:
The S61400-PB is a rear-end protection cap (end bell cover) designed for Kollmorgen S-series absolute encoders. It protects the rear shaft-side bearing and encoder electronics from dust, moisture, and mechanical damage in harsh industrial environments.
Detailed content
Model Breakdown:
- S61400 = Product Family (Encoder Accessory — Rear Cap)
- PB = Configuration Code: Protection Cap with Bore Seal (standard variant)
Technical Specifications:
| Parameter | Value |
|---|---|
| Compatible Encoder Series | Kollmorgen S61000 / S700 / S400 Series Absolute Encoders |
| Material | Anodized Aluminum 6061-T6 |
| Surface Finish | Black Anodized (RAL 9005) |
| Bore Diameter | Matches encoder shaft: typically 6mm or 8mm (model-specific) |
| Seal Type | Lip Seal (NBR rubber, 70 Shore A) |
| IP Rating (Installed) | IP65 (with seal engaged) |
| Operating Temperature | -20°C to +80°C |
| Weight | Approx. 0.08 kg |
| Mounting Method | Press-fit or set-screw (M3×0.5) |
Functional Features:
- Protects encoder rear bearing from contaminant ingress (dust, oil mist, coolant).
- Maintains IP65 environmental protection when installed on compatible encoders.
- Lip seal prevents lubricant leakage and external contamination.
- Lightweight aluminum construction adds minimal inertia to the system.
Structural Features:
- Cylindrical housing with O-ring groove for secondary sealing.
- Set-screw hole (M3) for locking to encoder housing.
- Drain hole (if applicable) to prevent pressure buildup.
Applicable Industries:
- Metal cutting (CNC mills, lathes)
- Press machines
- Welding robots
- Food and beverage (washdown environments)
- Woodworking machinery
Installation Requirements:
- Clean encoder rear face before installation.
- Apply thin film of grease (e.g., Klüber Isoflex NBU 15) on O-ring groove.
- Press-fit or tighten set-screw to 0.5 Nm torque.
- Verify shaft rotates freely after installation — no binding.
Usage Precautions:
- Do not use on encoders without rear bearing — will not seal properly.
- Replace seal if encoder has been submerged in coolant for extended periods.
- Do not over-tighten set-screw — risk of housing deformation.
