130x160x14.5 mm Crankshaft Rear Oil Seal 21440-2F050 PTFE, Aluminium Housing Assembly

Product Overview

This part is a complete crankshaft rear oil seal assembly for a 130 mm crankshaft journal in a 160 mm housing register. The sealing element is a PTFE lip carried in a cast aluminium housing, and the housing itself takes the mounting bolts, so the seal is bolted to the block instead of being pressed into a bore. A cable lead with a connector is part of the assembly.

At a glance:

130x160x14.5 mm | PTFE (polytetrafluoroethylene) lip in an aluminium carrier housing | assembly with bolt holes and an integrated cable lead | made in Xingtai, Hebei, China | working range -40 C to +150 C

VKEFOT supplies this assembly in Xingtai, Hebei, China for engine rebuilders, wholesalers and fleet workshops. Because the housing is bolted on, the bolt pattern and the housing register have to match the engine as well as the shaft diameter, so line up the part against the unit before ordering.

Key Features & Benefits

• PTFE lip for the crank position: PTFE takes the higher surface speed and the hotter oil found at a crankshaft end, and it seals with less friction than a rubber lip on the same shaft.
• Carrier housing in aluminium: The lip is set in a machined aluminium housing that bolts to the block, so the seal is located by the bolt pattern and the register rather than by press fit depth.
• Bolt holes in the housing: The mounting holes are part of the body, which keeps the seal square to the crankshaft axis and makes replacement a bolt on operation.
• Integrated cable lead: The assembly carries a cable lead with a connector, so the connection at the back of the engine is made with the seal in one operation.
• Built for the whole service life: The PTFE element covers -40 C to +150 C and holds its face under hot oil, which suits the temperature a crankshaft rear position sees.
• Assembly, not just a lip: Everything needed to close the rear of the engine arrives in one piece, so there is no separate carrier to clean or reseal on the bench.

The dimensions describe the sealing element: 130 mm shaft diameter, 160 mm housing register and 14.5 mm seal width. The aluminium carrier extends beyond these values, so confirm the bolt pattern, the housing register diameter and the connector type against your engine before ordering.

Material & Construction

The sealing element is PTFE (polytetrafluoroethylene), a fluoropolymer lip rather than a rubber moulding. PTFE covers a wider temperature band than NBR, from -40 C to +150 C, and holds its edge at the higher surface speeds found at a crankshaft end, with low friction against the journal. The lip is fixed in a cast aluminium housing that carries the mounting bolt holes and the cable lead. For a stationary sealing face on a hot, fast running shaft, PTFE is the material of choice; NBR is not used in this position.

Quality Control and Inspection

• Incoming: compound hardness checked before release to production.
• In process: housing machining and register diameter, lip form and edge condition, bonding of the lip to the carrier, bolt hole positions and cable lead continuity checked at set intervals.
• Final: dimensional check on inner diameter, outer diameter and seal width, housing register and bolt hole spacing, PTFE lip edge inspection, connector and lead check, marking, then packing count verification.
• Traceability: inspection results for each batch are recorded and kept; the inspection scope can be agreed before order confirmation.

Inspection records are kept per batch and stay traceable from the shipped goods. Third-party inspection before shipment can be arranged when it is stated in the enquiry.

Packaging, Carton and Delivery

Standard packing is individual polybag, inner carton, then export carton. Carton marks, labels and barcodes are printed to buyer specification.

Lead time for standard sizes is typically 7 to 15 working days after order confirmation, and longer for sizes that are not held as standard stock. Minimum order quantity depends on whether the size is a stocked standard or made to order. Pricing, MOQ, freight and trade terms are confirmed in the written quotation. Send an RFQ with quantity and destination port.

How to Order

The more of this you include, the faster and more accurate the quotation:

1. Size or OE number: 130 x 160 x 14.5 mm, or the number stamped on your current seal assembly.
2. Quantity and destination: required quantity, destination country and port.
3. Material requirement: PTFE as supplied for this assembly, or advise the engine duty if another lip material is needed.
4. Packaging requirement: carton marks, label data and barcode requirement.
5. Sample photo or drawing: where the assembly is matched from a removed original.
6. Operating conditions: engine type, sump oil temperature and connector type, if known.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Check the crankshaft journal diameter, the housing register diameter, the bolt pattern and the connector type against the removed assembly. The lip dimensions alone are not enough, because the carrier is located by the bolts.

What are the exact dimensions of this oil seal?
The sealing element measures 130 mm inner diameter, 160 mm outer diameter and 14.5 mm wide, with a larger aluminium carrier around it. Confirm the register and bolt spacing against your engine before ordering.

What is the minimum order quantity?
MOQ depends on whether the assembly is held as a stocked item or produced to order. State your required quantity and the MOQ and price steps are confirmed in the quotation.

What is the lead time, and can you ship by sea or air?
Confirmed orders are normally ready in 7 to 15 working days. Sea and air shipments are both arranged; freight cost and transit time are quoted for the destination port.

Can you supply FKM or HNBR instead of NBR?
This assembly is built with a PTFE lip, which is the material used at this position and covers -40 C to +150 C. If your duty calls for a different compound, tell us the operating conditions and we will confirm what can be produced.

Do you provide samples, and are they free?
Samples can be arranged for evaluation. Sample and freight charges are quoted per request, and on a confirmed bulk order the sample charge is normally set off against the order value.

Can you produce our packaging and logo?
packaging and logo available upon request.

What information do you need to quote?
The OE number or a photo of the removed assembly, engine type, quantity, sump oil temperature, packaging requirement, destination port and preferred Incoterm.
