Exalign Bearings

Arvis

FL Range 4 Bolt Flange Housings

FL Range 4 Bolt Flange HousingsPre-Mounted
Glacier DU or DX steel backed bearings are pre-mounted in captive inner members. Accommodate shaft misalignments up to 15

Self-Aligning
Precise positioning and accurate alignment during installation are unnecessary


High Performance
Eliminates edge loading thus allowing full use to be made of DU and DX performance

Long Life
DU and DX give long life with minimum maintenance. Sealing is unnecessary in most applications.

Easy Assembly
Working clearance of bearings on shaft eliminates press-fitting needed with some rolling element bearings

Economy
Standard stock sizes offered at low unit and low assembly costs. DU and DX ensure low operating costs.

Shaft Location
Shaft collar or shoulder can provide axial location where necessary. If moderate thrust is expected standard Glacier thrust washers can be included.

Standard Range
Three types - Plummer (or pillow) block, Four bolt flange mounting. Two bolt flange mounting.

Ex-Stock
Metric and Inch ranges available ex stock for nominal shaft diameters from 10mm to 100mm and 1/2" to 4".

Materials
Standard bearing housings are grey cast iron. Other materials are available (See 'Specials') Bearings can be specified in DU or DX material according to requirement. Both materials are supplied with pre-finished bores.

Selection
DU is a high performance dry-bearing material, used where lubrication is impracticable or undesirable and where the operating temperature is between -200C and +280C. DX gives outstanding performance when greased on assembly only. Re-greasing at extended intervals prolongs performance indefinitely. DX is suitable for operating temperatures up to 120C.

Specials
Pre-mounted self-aligning bearings other than the standards listed can be supplied to special order. more info use to be made of DU and DX performance

Exalign Load Ratings

Exalign Load RatingsEXALIGN HOUSING PERFORMANCE.

Estimated safe radial loads for exalign units based on the strength of the cast iron outer housing.

Glacier plain bearings materials can be used in high load applications. The maximum permissible loading for the bush, particularly at low rubbing speeds may exceed that for the Exalign housing or securing bolts.

  • Check from the table below that the load does not exceed the limit for the cast iron housing.
  • For full technical information on the various bushes, go to www.ggbearings.com
  • Note that the thermal conductivity of these units is such that, in the 'Application Factor' for both DU & DX calculations a housing of a 'Light pressing' nature should be used.

Materials

Standard bearing housings are made in grey cast iron. Other materials are available (See 'Specials') Bearings can be specified in DU or DX material according to requirement. Both materials are supplied with pre-finished bores

Selection

As a general guide on selection. DU is a high performance dry-bearing material, used where lubricant is impracticable or undesirable and where the operating temperature is between -200C and +280C. DX gives outstanding performance when greased on assembly only. Re-greasing at extended intervals prolongs performance indefinitely. DX is suitable for operating temperatures up to 120C.

Specials

Pre-mounted self-aligning bearings other than the standards listed in this leaflet can be supplied to special order.

Variations from standard include: Bearings for shaft diameters over 100mm - Split housings to allow for assembly in awkward locations or to provide a greater length of bearing. Housings with provision for re-greasing (As an alternative. re-greasing can be through shaft end drilling). Housing for special applications made in SG iron or corrosion resistant materials
