Daemar Seals
Daemar® stocks thousands of full range of DIN 3760 industrial shaft oil seals in many varieties and materials. No matter what the application, be it a new manufacturer or for maintenance, the right seal is a phone call away.
With shaft sizes ranging from 1/4” to 40” our 4 stocking facilities are ready to supply your JIT production or maintenance requirements.
DMR Rotary Shaft Seals
Since the introduction of synthetic rubber in 1938, seal manufacturers have researched the proper elastomeric properties required for effective sealing, Coupled with versatile designs we offer the following standard profiles. Custom designs or special applications can be reviewed with your engineering staff.
With Inch and Metric double, single, multi lip designs in stock our ability is almost endless.
If heat or chemical attack are a concern we offer viton, and polyurethane materials as well as the standard silicone and nitrile.
A-Series
The rubber elastomer outer covering tolerates thermal expansion as well as roughness in the housing bore. There will be no fretting corrosion. Furthermore, damage of the housing bore will be prevented when frequently replacing the seal. This qualifies for sealing gaseous or liquid media.
A Series
Single lip, spring-loaded design with inner metal case. Rubber cover O.D. Most economical general purpose seals.
Typical applications: engines, drive axles transmissions, pumps,electric motors and speed reducer.
Competitors types: SC, BA, WA, DG, CB, HMS4, Type 35, Model 92, BAUX2
AS Series
Double lip, spring-loaded design with inner metal case. Rubber cover O.D. . Provides light dirt exclusion on the second lip profile, retaining spring-loaded on the main lip.
Typical applications: engines, drive axles transmissions, pumps,electric motors and speed reducer.
Competitors types: TC, AS, BASL, WAS, DGS, CC, HMSA7, Type 32, Model 94, BAUSLX2
AO Series
Single lip,no spring, rubber covered O.D., improves sealing ability at the housing, and is kind to softer materials. The AO is for non-pressure applications only.
Typical applications: Ideal for grease retention or contamination exclusion.
Competitors types: VC, HM4, Model 91, WAO, BAOF
AOS Series
Double lip,no spring, rubber-covered O.D. improves sealing ability at the housing, and is kind to softer materials. The additional dust lip provides increased protection for the primary lip.The AOS is for non-pressure applications only.
Typical applications: Ideal for grease retention or contamination exclusion.
B-Series
Metallic casing enables easier fitting. However, this type of seal demands closer tolerances in the housing bore to ensure proper sealing on the outer covering.
B Series
Single lip,spring-loaded, precision ground O.D. with a lead-in chamfer to help ease the installation. Does not have the ability to seal around the O.D. like the rubber-covered seals, and is also not as kind to softer housing materials.
Competitors types: SB, B1, DF, BB, BE, WB, Type 44, Model 76, B1U, CRW1
BS Series
Double lip,spring-loaded, precision ground O.D. with a lead-in chamfer to help ease the installation. Does not have the ability to seal around the O.D. like the rubber-covered seals, and is also not as kind to softer housing materials.
Competitors types: TB, B1SL, DFS, BSL, BC, WBS, BES, CRWA1, Type 47, Model 78, B1USL
BO Series
Single lip, no spring, precision ground O.D. with a lead-in chamfer to help ease the installation. Does not have the ability to seal around the O.D. like the rubber-covered seals, and is also not as kind to softer housing materials.
Competitors types: VB, Type 71, Type 44, WBO, B1OF, HM14, HM21
BOS Series
Double lip, no spring metallic casing enables easier fitting. However, this type of seal demands closer tolerances in the housing bore to ensure proper sealing on the outer covering.
C-Series
Metallic casing with reinforcing cap. Sealing and mounting identical with type B. Preferentially applied in case of rougher operating conditions and where larger dimensions are utilized. Less delicate in case of incorrect mounting due to reinforcing cap.
C Series
Single lip, spring-loaded, precision ground O.D. with the addition of an inner case that provides increased structural rigidity and durability. This style is more often used in large-bore diameters or heavy-duty applications.
Competitors types: SA, SA2, B2, DFK, DB, CE, WC, CRWH1, Type 45
CS Series
Double lip, spring-loaded, precision ground O.D. with the addition of an inner case that provides increased structural rigidity and durability. This style is more often used in large-bore diameters or heavy-duty applications.
Competitors types: TA, TA2, B2SL, DFSK, CSL, WCS, DC, CRWHA1, Type 41
CO Series
Single lip, no spring, precision ground O.D. with the addition of an inner case that provides increased structural rigidity and durability. This style is more often used in large-bore diameters or heavy-duty applications.
COS Series
Double lip, no spring, precision ground O.D. with the addition of an inner case that provides increased structural rigidity and durability. This style is more often used in large-bore diameters or heavy-duty applications.
