UP004-2F Eccentric Lock Pillow Block Bearing 20mm 2F Double Steel Finger Sealed Zinc Alloy Housing

1. Product Overview

UP004-2F lightweight silver series pillow block bearing unit adopts integrated zinc alloy housing and U004 eccentric lock insert bearing, standard 20mm metric bore, matched with upgraded dual-side 2F steel flinger composite sealing structure. It is widely used in light conveyor equipment, small agricultural machinery, packaging machines and mini automation equipment requiring compact installation space.

Suffix `2F` stands for double-sided steel centrifugal flinger + multi-lip NBR rubber composite sealing system. It effectively blocks mud, crop debris, dust and splashing water, far better sealing performance than standard single lip seal, perfectly adapted to dusty farm, workshop and outdoor light-duty working environments.
Lightweight die-cast zinc alloy housing features compact structure, built-in center alignment mark for fast positioning during installation. Eccentric locking collar clamps the shaft evenly by rotating along the running direction, stable anti-slip effect for both forward and reverse rotation equipment. Standard model without grease nipple, pre-filled long-life anti-wear lithium grease at factory for maintenance-free operation. All rolling parts are made of fully quenched GCr15 bearing steel with superfinished raceway, stable light load bearing capacity and long service life.

Light-duty matching guide and 2F seal durability test reports can be provided upon customer request.

3. Core Advantages

• Compact lightweight zinc alloy housing, smaller volume and lighter weight than cast iron pillow blocks, saves installation space for mini machinery.
• Upgraded 2F dual steel flinger composite sealing system: outer steel flinger blocks large dust and mud residues, inner multi-lip rubber seal isolates fine dust and splash water, ideal for dusty outdoor light equipment.
• Eccentric collar locking design provides uniform shaft clamping force, no shaft surface damage, stable anti-slip performance under frequent start-stop and slight vibration, fits bidirectional rotation.
• Housing with center positioning mark, simplifies installation alignment and shortens assembly time for mass production lines.
• Factory pre-filled high-viscosity long-life lithium grease, standard model without grease fitting, realizes long-term maintenance-free operation.
• Fully quenched bearing steel rolling elements reach HRC60–65 hardness, excellent anti-indentation and fatigue resistance, stable service life for light load continuous operation.
• Fully interchangeable with global standard UP004 series pillow block units, direct replacement for original equipment without structural modification.
• Complete customized service: stainless steel anti-corrosion housing upgrade, OEM laser marking on housing, neutral export carton anti-rust packaging, high temperature special grease filling.
