UKFL200+H Series 2-Bolt Flange Bearing Units — Tapered Bore, Adapter Sleeve Locking
The UKFL200+H series applies the adapter sleeve locking principle of the UKP200+H and UKF200+H to the two-bolt oval flange housing. The adapter sleeve mounts on the shaft without any shaft surface preparation, distributes clamping load over the full sleeve contact length on removal, and leaves the shaft surface undamaged — making UKFL200+H the preferred choice for oval flange-mounted bearings on rough-turned shafts, shafts that will be reused, or retrofit installations where shaft reconditioning is not viable. The H-suffix sleeve variants (H2305, H2306, …) follow the same HS/HA/HE system as the UKP200+H and UKF200+H, allowing multiple shaft diameter ranges to be served from the same housing size.


Key Features
🔒
No Shaft Surface Damage
Adapter sleeve distributes clamping over full contact length. Removal leaves no marks. Suitable for rough-turned, as-machined, or reused shafts.
⚙
1:12 Self-Locking Taper
Taper locks the sleeve under operating loads without relying solely on bolt friction.
◯
UCFL200-Identical Oval Housing
H, J, bolt-circle match UCFL200 for equivalent bore sizes. Existing oval flange bolt positions reusable when upgrading to adapter sleeve locking.
↔
Multiple Sleeve Options Per Housing
HS, HA, HE sleeve variants cover different shaft diameter ranges within the same housing.
📏
Metric and Inch Bore
20–70 mm metric bore with inch bore variants per housing size.
✅
GB / ISO / DIN / BS Compliant
Adapter sleeve dimensions per international standards.

Applications
⛏
Mining & Quarry Oval Flange Supports
Shaft supports on vertical panel-frame structures where shafts are rough-turned and shaft surface preservation between replacements reduces operating costs.
🏛
Cement & Process Plant Oval Flange Mounts
Fan and auxiliary shaft oval flange supports on vertical frame panels where abrasive contamination makes shaft preservation important.
🌿
Agricultural Implement Oval Flange Positions
Shaft oval flange supports on implement frames where shafts are manufactured to commercial tolerances and the adapter sleeve avoids post-machining rework.
⚙
Pump Frame Oval Flange Supports
Pump shaft oval flange supports where the adapter sleeve allows precise bearing positioning at assembly without shaft-machined shoulders.
💧
Infrastructure Long-Life Oval Flanges
Oval flange supports in water treatment and irrigation where minimal shaft damage on removal supports multi-decade equipment service.
🧱
Retrofit on Worn Shaft Oval Flanges
Replacement oval flange bearings on shafts with minor surface wear where the adapter sleeve bridges irregularities preventing setscrew locking.
