Bearing Assembly Product #2a – Offshore Application
Product Overview
The Bearing Assembly Product #2a is a manually latched sealed bearing assembly engineered for land drilling Rotating Control Device (RCD) systems operating under elevated pressures and rotary speeds. Designed to simplify installation and reduce equipment requirements, the assembly delivers reliable annular sealing and secure closed-loop drilling performance without the need for hydraulic power systems.
Key Features
- Compatible with all land drilling applications and up to 5 7/8" drill pipe
- Field-configurable for single or dual drill pipe seal configurations
- Sealed bearing design eliminates need for external lubrication
- Patented Multi-Seal Cartridge with pressure-compensated dynamic sealing
- Manual clamp assembly for latching and unlatching operations
- No HPU required for installation or retrieval procedures
- Designed for high-load and high-rotation drilling environments
- Supports natural and polyurethane drill pipe seals
- Full range of compatible RCD accessories available
- Designed and manufactured in compliance with API Specification 16RCD
Applications & Drilling Scenarios
- Land drilling operations requiring simplified RCD systems
- Applications where hydraulic infrastructure is limited or unnecessary
- Managed pressure drilling (MPD) operations
- Closed-loop drilling applications requiring annular sealing
- High-rotation drilling environments with elevated pressure conditions
- Operations prioritizing simplified rig-up and maintenance procedures
Advantages
- Manual clamp design eliminates need for hydraulic latch systems
- Reduced equipment requirements simplify rig operations
- No external lubrication requirements reduce maintenance complexity
- Pressure-compensated sealing extends bearing life
- Reduced replacement frequency lowers operating costs
- Supports both single and dual seal configurations
