11. FAQ: 40×80×7 TCV Oil Seal High Pressure Oil Seal Cfw Babsl 40*80*7 for Hydraulic Pump Seal

Q1: What is the difference between CFW and Babsl profiles in this oil seal?

CFW and Babsl refer to the sealing lip structure. CFW is a proprietary design ensuring robust dust and oil separation for high-pressure, high-speed scenarios. BABSL denotes an additional dust lip, further reducing contamination ingress for extended lubricant retention. Both are available in the 40×80×7 TCV Oil Seal High Pressure Oil Seal Cfw Babsl 40*80*7 for Hydraulic Pump Seal product.

Q2: Which materials are most suitable for aggressive chemicals or high-temp?

For mineral/hydraulic oils, NBR offers excellent resistance. For temperatures up to 200°C or acidic media, FKM (Viton®) or PTFE is preferred. All options are available for 40×80×7 TCV Oil Seal High Pressure Oil Seal Cfw Babsl 40*80*7 for Hydraulic Pump Seal, see full specs here.

Q3: What installation standards must be observed?

Follow ISO 6194 and DIN 3760 for dimensional/interference fits. Shaft surface finish (Ra 0.2–0.8 µm), perpendicularity, and correct lubrication during installation are critical for optimal life, especially in high pressure applications.

Q4: What are typical dimensions and tolerances?

This product has nominal ID/OD/thickness of 40×80×7mm. Manufacturing applies ISO 2768-mK for machined parts, with overall tolerance usually ±0.02mm (seal lips), ±0.05mm (cage bodies).

Q5: How does the high-pressure oil seal reduce energy consumption?

By minimizing leakages and offering low friction (due to precision garter spring), 40×80×7 TCV Oil Seal High Pressure Oil Seal Cfw Babsl 40*80*7 for Hydraulic Pump Seal improves pump volumetric efficiency, reducing energy draw by up to 8% in continuous operation (source: OEM field data, 2023).

Q6: Is there anti-corrosion protection?

Yes, with optional stainless steel inserts and anti-oxidant rubber blends, this oil seal maintains full function even in saltwater or mild acid/alkali conditions. SGS corrosion stability reports available on request.

Q7: What is the delivery and packaging standard?

Bulk or single-seal packaging, inert atmosphere/vacuum packing for export. Standard delivery is 4-12 days. Barcoded/traceable labeling for all sizes.
