This bearing is widely used in various small and medium-sized mechanical equipment, household appliances, power tools, and precision instruments. Typical industries include general machinery manufacturing, automotive components, household appliances (such as washing machines and fans), office automation equipment, ventilation systems, and small motor drive fields. Its design balances versatility and reliability, making it a standard component for rotating support structures in numerous industrial and consumer products.
Product structure:
The main structural parameters of the MR126 2RS bearing are: 6mm bore diameter, 12mm outer diameter, and 4mm width. It adopts a standard deep groove ball design, with steel balls evenly arranged by a cage. Its core feature is the inclusion of contact rubber seals (2RS) on both sides, which effectively prevent internal grease leakage and block the ingress of external dust and contaminants. The bearing rings and steel balls are typically made of high-carbon chromium bearing steel, heat-treated to achieve high hardness and wear resistance.
Key performance features:
This bearing offers smooth operation, low friction coefficient, low noise, and low temperature rise. The double rubber seal design provides excellent dust and water protection, extending the bearing’s service life and maintenance intervals in harsh environments. It features good adaptability to high-speed rotation and certain radial and axial load-carrying capacities. Pre-filled with high-quality grease, it is ready for immediate use and often achieves lifelong lubrication in most applications with minimal maintenance requirements.
Main application scenarios:
It is primarily used for rotor support in small AC or DC motors, drive shafts in household appliances (such as juicers and food processors), various small pulley or gear transmission systems, wheels on light-duty transport equipment, and rotating parts of precision instruments requiring dust protection. It is an essential basic component in automation equipment, low-power drive devices, and durable consumer goods.
Technical Specifications and Requirements:
The bearing must conform to international general standards such as ISO 15:2011 (Rolling bearings — Radial bearings — Dimensions and tolerances). Internal clearance is typically in the standard CN group. The rubber seal material must be oil-resistant and anti-aging. The operating temperature range is generally between -30°C and +110°C, depending on the grease and seal material. During installation, dimensional accuracy and coaxiality of the shaft and housing must be ensured, avoiding direct application of improper mounting forces on the seals. Storage should be in a dry environment to prevent corrosion.
