T01-00375EAA Turntable Bearing

T01-00375EAA is a Reali-Slim TT turntable bearing. The configuration identifies Bearing Type: Standard, Construction: Single Row, Row Type: Single, and Series: TT Series. It provides a rotating joint between supported structures. The contact arrangement, the ring mounting interfaces and the drive connection must be selected together, rather than treating the outside envelope as the complete specification.

Contact Arrangement and the Supported Joint

T01-00375EAA identifies Type: Ball, For Load Direction: Four Point Contact, and Inner Ring Type: Standard. The Reali-Slim TT turntable identity makes the axial package and the two ring attachment interfaces central to selection. A compact envelope does not remove the need for flat support and controlled alignment. Ring deflection can alter the working contact relationship under combined loading.

Preserve any explicit contact arrangement and row description with the exact turntable designation. Thin axial packaging is not evidence of an installed preload, accuracy class or torque limit. The bearing and its surrounding support must be assessed as a joint rather than as an isolated outline.

Drive Interface and Gear Geometry

T01-00375EAA identifies external gear. The mating drive works at the outward-facing tooth interface; clearance for the mesh belongs outside the ring envelope and must follow the actual moving members. The mesh geometry identifies Pitch Diameter Of Gear: 4.547″ and Number Of Teeth: 291. Pitch diameter and tooth count describe the mesh, not the bearing mounting diameter or a permissible rotation speed.

Assess the actual tooth interface with the selected mating drive. Tooth geometry, flank contact and backlash must agree with the mating drive. A tooth-force entry is not an overall torque guarantee. Support deflection can change the mesh, so the bearing seating and the gear alignment need to be checked together.

Envelope and Individual Ring Interfaces

The main envelope of T01-00375EAA identifies Inside Diameter Of Inner Ring: 3″, Outside Diameter Of Outer Ring: 4.578″, and Height Of Overall Bearing Assembly: 0.25″. The inner opening, outer envelope and axial package serve different layout checks. None should be substituted for a mounting-hole circle or gear pitch diameter. Allow room for adjacent members over the full intended motion, not only in one static position.

Ring-specific geometry identifies Internal Diameter On Outer Ring: 3.648″ and External Diameter On Inner Ring: 3.856″. Ring heights and raceway diameter have their own roles and are not interchangeable with overall assembly height or an opening diameter. Check axial overlap and radial clearance against the actual interfaces. Preserve the stated units for each dimension rather than converting a measurement-system label into a unit for another value.

Attachment Patterns and Installed Geometry

The inner-ring attachment identifies Bolt Circle In Inner Ring: 3.313″ and Number Holes In Inner Ring: 10. The outer-ring attachment identifies Bolt Circle In Outer Ring: 4.188″ and Number Holes In Outer Ring: 14. The two ring attachment interfaces are separate connections. Match each stated circle, quantity and hole form to its own supporting member; do not exchange inner and outer patterns because the nominal bearing size agrees.

Establish the required seating and installed running condition with the joint design. Tolerance, clearance and runout describe different checks. Flat backing, fastener load and structural stiffness influence installed geometry; a nominal dimension does not establish a bolt torque or an assembled preload. Confirm seating and alignment before applying normal duty.

Rating Direction and the Combined Duty

Axial entries for T01-00375EAA identify Basic Dynamic Load Rating(Ca): 980 lbs and Basic Static Load Rating(C0a): 2130 lbs. The distinct radial entries identify Basic Dynamic Load Rating(Cr): 1110 lbs, Dynamic Radial Load: 700 lbs, Basic Static Load Rating(C0r): 2850 lbs, and Static Radial Load: 1140 lbs. Keep dynamic and static bases separate when checking the duty. Where more than one rating notation is given, retain each notation rather than treating the values as interchangeable or assigning a new rating basis.

Moment-related entries identify Moment Load Rating: 980 ft-lbs. Joint loads must be checked with support deflection and the fastener system. Separate maximum values do not prove simultaneous capacity, fatigue life or a speed limit. Bearing reaction data must be used with the stated contact arrangement; an unrelated rating direction cannot supply a missing operating limit.

Lubricant Access and Handling

Lubrication and contamination control must suit the working contacts and the installed position of T01-00375EAA. Plan lubricant access through the actual assembly design; no fitting quantity or replenishment interval follows from the bearing designation. A seal-material name is not an ingress-protection rating. Lubricant compatibility and contamination control must be assessed for the installed environment.

The stated weight is 0.59 lbs. Handling and seating should preserve the ring faces and working geometry. Use the applicable lifting and mounting procedure, without assigning lifting points or tooling from the bearing name. Mounting forces should act through the member being seated rather than across rolling contacts. After installation, check motion, alignment and lubricant access before introducing the intended load.

Putting the Joint Specification Together

Select T01-00375EAA as a Reali-Slim TT turntable bearing with external gear. The decision should connect contact geometry, the two ring interfaces, the mounting support and the applicable load case. Compare the exact tooth and attachment data when considering a replacement; an equal outside diameter or similar family name cannot prove interchangeability.

Before release, retain the exact designation with the ring dimensions, distinct rating bases and ordered material configuration. Verify the mating design, fastening assessment, gear mesh where present and installed running condition. These checks establish a coherent rotating-joint specification without turning general engineering function into approval for a particular machine or operating environment.
