Generally consists of three parts: oil seal body, reinforced skeleton and self-tightening coil spring. The sealing body is divided into bottom, waist, cutting edge and sealing lip according to different parts. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain“interference”. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will generate a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate the self-tightening force of the oil seal at any time. Brief description: Brand: J-type frameless Model: GJF/GJFR Oil seal Use: Other materials: Applicable models: Bearings, rollers, others TRL type CFW—Simmerring R35 type R37 type 2. Features: It is mainly used in the transmission part of rolling mills and heavy machinery. The oil seal has an outer edge shoulder reinforced with clip cloth, which is tightly integrated with the rubber sealing lip, and uses a spring to give the sealing lip With preload 3. Material: use nitrile rubber + nitrile rubber seals
cloth for temperature below 100 ℃, fluorine rubber + fluorine rubber cloth for temperature below 200 ℃ The lip is highly wear-resistant * the radial contact pressure of the sealing lip is durable * the sealing effect is good Sealing material of rotating shaft: nitrile rubber Product hardness: 80±5°A Working pressure:≤0.03Mpa Working temperature: -40~+120℃ Standard source: HG4-338-66 The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain“interference”. Company website: https://www.orksealing.com/
