SY2TFVA228 High Temperature Pillow Block Bearing Unit 50.8mm Bore Solid Lubricant Set Screw Lock

1. Product Overview

SY2TFVA228 (SY2.TF/VA228) is integrated high-temperature plummer block bearing unit, composed of cast iron TF series pillow block housing and high temperature resistant YAR211-200-2FW/VA228 spherical insert bearing, shaft bore size 50.8mm (2 inch).
Suffix code explanation:

• SY: Standard pillow block bearing unit series
• TF: Cast iron two-bolt pedestal housing, stable rigid structure for horizontal mounting
• VA228: High temperature special configuration, solid graphite composite permanent lubricant, double-sided metal flinger + reinforced heat-resistant sealing, working temperature up to 350°C continuous operation

The insert bearing features double extended inner ring with dual M10 set screw locking structure, spherical outer surface matching housing inner spherical bore to realize self-alignment, compensating shaft installation parallel and angular offset errors. No regular grease refilling required, solid lubricant provides long-lasting lubrication under high heat environment, effectively avoiding grease carbonization failure in high-temperature equipment. Widely applied to industrial furnaces, drying ovens, heat treatment production lines, baking equipment, high-temperature conveyor rollers, kiln transport machinery and all continuous high-temperature operating equipment.

2. Technical Specifications

Mounting dimension drawings, high temperature installation operation guides and heat resistance performance test reports can be provided on customer request.

3. Core Advantages

1. VA228 high temperature special configuration, built-in solid graphite permanent lubricant, no frequent oil filling, effectively prevent ordinary grease from drying, coking and losing lubrication under long-term high temperature working condition.
2. Double-sided composite heat-resistant sealing + metal anti-dust flinger dual barrier structure, block high-temperature dust, furnace flue gas and tiny oxide debris from entering bearing internal raceway, extend service life of insert bearing.
3. TF cast iron integrated pedestal housing, thickened wall structure with strong rigidity, stable anti-vibration performance, uniform load distribution during high-temperature continuous operation, not easy to deform under thermal expansion.
4. Spherical outer surface self-aligning insert bearing design, automatically absorb shaft assembly offset, eliminate abnormal wear caused by installation error and equipment thermal deformation.
5. Dual M10 set screw locking on double extended inner ring, uniform clamping force on shaft surface, firm locking under high temperature and vibration, prevent bearing inner ring slipping and shaft abrasion.
6. Standard inch bore interchangeable overall dimension, fully compatible with global SY2.TF/VA228 pillow block units, direct replacement without modifying equipment mounting bracket structure.
7. High temperature special quenched steel rolling components, stable metallographic structure, excellent high temperature wear resistance and contact fatigue resistance, avoid early raceway peeling under thermal cycle load.
8. Rich customizable options: Custom high temperature solid lubricant ratio, stainless steel insert bearing upgrade, OEM laser marking on housing, neutral anti-rust export carton packaging, customized special high temperature sealing structure.
