TA Oil Seal
Details
TA Oil Seal is a single-skeleton rotary oil seal with exposed solid metal outer casing, engineered for precision-machined rigid housing installation. The rigid metal outer ring delivers precise dimensional positioning and high assembly structural strength, paired with spring energized sealing lip to lock internal lubricants and block external dust. It is the preferred sealing part for equipment requiring long-term dimensional stability and high mounting rigidity.

Description

DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of ta oil seal in China. If you're going to buy bulk ta oil seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.

 

TA Oil Seal adopts exposed all-metal outer diameter + single spring sealing lip integrated structure, completely different from full-rubber covered SC oil seal. The thick metal outer shell features high hardness and structural rigidity, achieving zero clearance tight fit with precision machined steel or cast iron housing bores, without radial expansion or deformation during long-term operation. The built-in stainless steel garter spring applies constant radial preload on the inner sealing lip, ensuring sustained close contact with rotary shafts to prevent lubricant seepage under light internal pressure. The outer lip edge forms a simple dust barrier to block floating dust and light splashing impurities, protecting the main sealing edge from abrasive scratches. Two mainstream elastomer formulas (NBR, FKM) are available to match normal-temperature general equipment and continuous high-temperature precision transmission machinery.

 

Design Advantages

 

Solid exposed metal outer casing, outstanding structural rigidity and permanent dimensional stability

Precise interference fit with precision machined rigid housings, no housing bore deformation after long running

Spring-energized inner lip maintains consistent shaft contact force for stable oil retention performance

Simple dust blocking edge reduces external pollutant intrusion and extends seal service life

Hard metal outer ring resists extrusion deformation during press-fitting installation

Compact single-lip layout, low friction loss, suitable for medium-speed precision rotary equipment

 

Typical Applications

 

 

  • All types of industrial gearboxes and speed reducers with precision cast iron housings
  • Industrial fluid transfer pumps, water pumps and hydraulic oil pumps
  • Standard driving electric motors with steel housing
  • CNC machine tools, machining centers and precision spindle assemblies
  • Reciprocating air compressors and rotary compression equipment
  • Precision power transmission assemblies for automated industrial machinery

 

FAQ

 

 

Q1: What are the structural characteristics of rotary sealing components with half-covered metal outer frame?

A1: The outer metal frame is partially exposed, and the outer side is partly wrapped by rubber material. This design improves static-sealing performance between outer circle and housing bore, and maintains good dimensional stability from metal support.

Q2: What practical benefits does dual-lip structure bring for rotary sealing parts?

A2: The inner lip locks lubricant inside the equipment. The outer auxiliary lip blocks dust, splash and moisture from outside. It realizes inner oil-locking and outerpollution blocking for general transmission equipment.

Q3: Is it necessary to add lubricant during TA oil seal installation?

A3: Yes. Smear a small amount of compatible lubricant on sealing lip before assembly. Avoid dry friction at initial startup, which prevents lip burning and early-stage leakage.
