Product Description
Shimano 10T2K Ball Bearing | Heavy-Duty Spool & Drive Support
The Shimano 10T2K Ball Bearing is a high-performance, marine-grade internal component found in Shimano’s heavy-duty overhead and lever drag reels. It is a vital structural part designed to support high-torque shafts, ensuring smooth rotation under the extreme loads encountered during offshore big-game fishing.
This bearing is the modern global replacement for several legacy part numbers, including BNT3633, TGT1573, and RD11424. Known for its durability and precision, the 10T2K is typically manufactured in Thailand to strict Shimano OEM standards.

Compatible Reel Models
The 10T2K is a specialized bearing found primarily in larger, high-capacity reels. It is a direct fit for:
-
Shimano Talica: TAC-12, TAC-12II, TAC-16, TAC-16II (Used in the main drive or spool support).
-
Shimano Ocea Jigger: LD 2500HG (Modern lever drag models).
-
Shimano Baitrunner: 4500A, 6500A (Spool shaft bearing).
-
Shimano Trinidad/Torium: Select large-frame models (Verify by schematic).
Maintenance & Lubrication Recommendation
Because this bearing is often located deep within the drivetrain or supporting the main spool shaft of an offshore reel, it is subject to heat from friction and salt crystallization. We recommend Deuthlon Lubricants:
-
For Maximum Longevity: Apply a light coating of Deuthlon Reel Gear Grease to the exterior shields of the bearing before installation. This provides a "salt-block" barrier that prevents moisture from reaching the internal races.
-
Internal Lubrication: For the internal balls, use Deuthlon Power Cast Oil. This ultra-thin lubricant ensures the bearing spins with zero resistance, which is critical for the "free-spool" performance required in live-bait fishing.
-
Signs of Failure: if the reel makes a "whirring" noise or feels rough when the spool is spinning freely, this bearing likely has salt pitting and should be replaced rather than cleaned.
Why Use Genuine Shimano 10T2K?
-
High Load Capacity: Specifically sized (9x20x6mm) to handle the lateral pressure of high-drag settings (up to 40+ lbs) without deforming.
-
Precision Tolerance: Ensures perfect alignment of the drive shaft, preventing the gear-to-pinion "mesh" from slipping under pressure.
-
OEM Material: Crafted from a specialized stainless steel alloy that outperforms generic hardware-store bearings in high-salinity environments.
