Sphere-Rol® Bearings

· Invented by McGill Designed per the highest engineering and quality

standards in the bearing industry

· Sealed design utilizes a single row of spherical rollers

Can be installed in applications where a sealed, dual row configuration is too wide for use

Three readily available integral seal options eliminate the need for special re-designs when changing from unsealed competitive bearings

· Better misalignment capability than competitive bearing designs

· Dimensionally equivalent to unsealed dual row designs

Sphere-Rol ® ValueSphere-Rol ® Value

Only “off the shelf” Sealed Spherical Roller Bearing

Dimensionally Interchangeable With Double Row Unsealed Designs

– The dimension of Sphere-Rol®

bearings with integral Nylaplate seals meet ABMA/ISO specifications. This feature removes the need for special redesigns when changing from unsealed competitive bearings.

Integral Seals can Reduce OEM Costs in Four Ways

– Cost of external seals eliminated

– Seal housing cost eliminated

– Housing machining costs reduced

– Faster design time

Three seal options– NYLAPLATE® seal

– NYLAPLATE® high temp seal

– LAMBDA® seal

NYLAPLATE® Seal

– Combined labyrinth and contact seal

– Vents help reduce seal blow during re-lubrication

– Temperature rating of -30° to 300°F (-35° to 150°C)

– Specify suffix “S” or “SS”

• Ex SB-22308-W33-SS

NYLAPLATE® High Temperature Seal

– Temperature rating of 300° to 450°F (150° to 230°C)

– Also suited for chemical contamination

– Specify suffix “TS” or “TSS” along with a grease code suffix

• Ex SB-22308-C3-W33-TSS-VA

• VA is a standard high temp grease

Both have a max misalignment capability of ± 2° for best seal performance

LAMBDA® Seal– For heavier contamination, including moisture

Triple Seal Effect– NYLAPLATE® Seal

– Grease dam

– LAMBDA® Seal

Temperature rating of -30° to 300°F (-35° to 150°C)

± 1° Maximum Misalignment

Specify suffix “YS” or “YSS”– Example SB-22308-C3-W33-YSS

Consider boss diameter of seal

Sealed bearings are factory filled with grease– -S, -SS, -YS, -YSS bearings filled

with #2 EP grease, -30° to 350°F (-35° to 150°C)

– -TS, -TSS bearings filled with high temp grease (VA), 40° to 450°F (4° to 230°C)

W33 feature used for bearing lubrication– Groove in outer ring with oil holes

Relubrication of bearing dependent on speed, temperature, environment, loads

In many cases, bearing will need some re-lubrication interval

Single row design allows for greater misalignment capability than a dual row design

Conventional spherical roller with dual roller configuration ±1 ° to ± 2° misalignment

Sphere-Rol® Up to ± 3° misalignment in unsealed bearing

Up to ± 2° misalignment with NYLAPLATE® seal

Up to ± 1° misalignment with LAMBDA® seal

Single row design has more space for misalignment
