130x160x14 mm HTC Rotary Shaft Oil Seal NBR, Threaded Inner Lip Rubber-Covered Seal

Product Overview

A 130 x 160 x 14 mm HTC oil seal is a large diameter radial shaft seal for a 130 mm shaft in a 160 mm bore, used where a big housing has to be closed against oil loss. The inner lip carries a moulded thread or spiral, so oil that creeps under the lip is pumped back toward the oil side as the shaft turns. The outer diameter is rubber covered and the body is 14 mm wide.

At a glance:

130x160x14 mm | NBR (nitrile butadiene rubber) | HTC body, threaded inner lip, rubber-covered outer diameter, single lip with garter spring | made in Xingtai, Hebei, China | working range -30 C to +100 C (short peaks to +120 C)

VKEFOT produces this size in Xingtai, Hebei, China for reducer builders, axle workshops and parts distributors working on large equipment. Because the lip is threaded, the direction of shaft rotation matters as well as the three dimensions, so mention the rotation direction when you enquire.

Key Features & Benefits

• Threaded inner lip: The moulded spiral on the lip pushes oil back toward the sump as the shaft turns, which reduces weeping on large diameter, slow turning shafts.
• Rubber-covered outer diameter: The rubber jacket grips the housing bore and takes up light scoring and surface marks, so an older housing can often be sealed without re-machining.
• Spring-loaded lip: A garter spring keeps the lip pressed against the shaft as the rubber beds in, so the seal does not lose contact after the first running hours.
• Built for large bores: At 130 mm inner and 160 mm outer diameter the seal covers reducers, axles and industrial gear housings where small seals are not used.
• NBR for gear oil duty: The nitrile element handles mineral and gear oils from -30 C to +100 C, with short peaks to +120 C, and stays supple in cold starts.
• One size, easy replacement: The 14 mm body matches a plain housing seat, so a worn seal can be exchanged by measurement with no housing changes.

Dimensions are nominal production values written as inner diameter x outer diameter x width. The threaded inner lip is rotation direction sensitive, so confirm the turning direction of the shaft as well as the three measurements before releasing an order.

Material & Construction

The element is moulded from NBR (nitrile butadiene rubber) over a metal insert and covered by a rubber jacket on the outer diameter. NBR resists mineral oil, gear oil and grease within -30 C to +100 C, with short peaks to +120 C, and copes with the small shaft runout found on large worn housings. The inner lip is moulded with a thread that returns oil to the sump, and a garter spring keeps lip load steady. Where the housing runs hot or carries synthetic oil, the same body can be quoted in FKM (fluoroelastomer), which holds continuous duty to about +200 C.

Quality Control and Inspection

• Incoming: compound hardness checked before release to production.
• In process: insert concentricity, lip geometry, thread form on the inner lip, spring seating and rubber jacket thickness checked at set intervals.
• Final: dimensional check on inner diameter, outer diameter and width, rubber hardness, thread direction check, lip edge inspection and 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 held per production batch and can be traced to the delivered shipment. Third-party inspection before loading can be arranged when it is requested 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 mm, or the number stamped on your current seal.
2. Quantity and destination: required quantity, destination country and port.
3. Material requirement: NBR as standard, or FKM for higher oil temperature or synthetic lubricant.
4. Packaging requirement: carton marks, label data and barcode requirement.
5. Sample photo or drawing: where the housing is matched from a worn original.
6. Operating conditions: shaft rotation direction, oil temperature, lubricant type and shaft speed, if known.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Measure the shaft, the housing bore and the seat depth, then check the lip against the seal you removed. On this part also note which way the shaft turns, because the threaded inner lip is made for one rotation direction.

What are the exact dimensions of this oil seal?
130 mm inner diameter, 160 mm outer diameter and 14 mm width. Confirm the measurements on your own shaft and housing, since housing depth and shoulder position differ between applications.

What is the minimum order quantity?
MOQ is set by the size and by whether it is a stocked standard or produced to order. Send the quantity you have in mind and the MOQ and price steps come back with the quotation.

What is the lead time, and can you ship by sea or air?
Normal production and packing time is 7 to 15 working days after confirmation. Sea and air freight are both arranged, with cost and transit time confirmed against the destination.

Can you supply FKM or HNBR instead of NBR?
Yes. FKM or HNBR can be supplied in the same geometry where the oil temperature or the lubricant goes beyond the NBR range. Confirm the compound when you enquire.

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

Does the helical return groove require a specific rotation direction?
Yes. The thread on the lip is cut for one direction of shaft rotation, so state the turning direction when you order. A seal fitted against the rotation direction will push oil outward instead of returning it.

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