Floating Seal 210.50mm for BHS Mixer Shaft End

Introduction

The floating oil seal consists of two identical alloy steel rings and two rubber rings. The working principle is that under the support of a pair of metal rings, a pair of rubber rings form a closed space (but not in contact with the shaft) with the cavity. When it operates, the metal ring two grinded surfaces are closely matched and moved relatively to each other. They ensure good operation, and effectively isolate external dust, water, mud, and protect the internal grease from leaking.

DO type is a common floating oil seal. It consists of two tapered cross section seal rings and two O-rings.

Applications

Floating oil seals are widely used for applications with slow speeds and high requirements for lubrication reliability and life. For example,

  • Mining equipment: heavy truck, electric shovel, drilling rig, coal mining machine, scraper conveyor, screening machine, crusher, etc.
  • Construction machinery: hydraulic excavator, bulldozer.
  • Agricultural machinery: wheeled tractors, cultivators, trenchers, lawn mowers.

Material:

The material of the metal ring is alloy steel 100Cr6 that conforms to the UNI3097 standard, and the hardness is HRC58-HRC63; the material of the rubber ring is nitrile rubber.

Working conditions:

  • Working pressure: ≤3 bar
  • Working temperature: -30 — + 110 ° C (NBR) -25 — + 200 ° C (FPM)
  • Surface speed: ≤3m / s
  • Surface roughness: The surface roughness close to the seal ring is recommended to be Ra4.0-6.5.

Installation guide:

— Thoroughly clean the cavity parts to remove any residue. All edges of the groove must be smooth.

— Open the original packaging just before installation.

— Check the position of the O-ring to confirm it is not distorted. Put half of the seal into the cavity entrance and press it evenly into the cavity. Wet the groove and rubber ring with absolute ethanol to facilitate installation. Lubrication is strictly prohibited during installation.

— Check whether the outer surface of the groove and the sealing are parallel when the installation is done. The maximum deviation is 1MM. The O-ring must not have any undulations and protrusions in the groove.

— Press the sealing rings on both sides tightly, clean the sealing surface, and smear a thin oil film on the sealing surface with a lint-free cloth.

— Check the clearance after installation and calculate the amount of compression.
