6306 2RS High Quality Deep Groove Ball Bearing 30X72X19 Overview

Engineered for reliability and versatility, the 6306 2RS High Quality Deep Groove Ball Bearing 30X72X19 is a standard-size bearing widely adopted across Basic component manufacturing and Rolling bearing manufacturing. With a 30 mm bore, 72 mm outside diameter, and 19 mm width, its deep groove geometry supports radial loads and moderate axial loads in both directions. The “2RS” double rubber seals retain grease and block contaminants, making it a dependable choice for dusty, wet, or mixed-service environments common in conveyors, pumps, electric motors, gearboxes, and agricultural equipment.

Technical considerations include high-purity chrome steel rings and balls (commonly AISI 52100/GCr15), precision finishing of raceways for low noise, and a steel cage for stability at speed. Typical configurations are available in ISO 492 tolerance classes (P0/P6) and internal clearances (C0/C3) to suit load and temperature profiles. Factory-filled NLGI-2 premium grease supports long service intervals, while the contact seal design helps preserve lubricant life. As a manufacturer with strong process control and OEM capability, Xingtai Botong Machinery Technology Co., Ltd delivers consistent quality, traceability, and flexible packaging/branding to fit industrial supply chains.

Benefits & Use Cases of 6306 2RS High Quality Deep Groove Ball Bearing 30X72X19 in Rolling bearing manufacturing

In rolling bearing manufacturing, the 6306 2RS serves as a high-volume, high-utility reference item that fits numerous platforms. OEMs and MRO teams specify it for electric motors (quiet running and low vibration), belt-driven conveyors (robust sealing against dust), agricultural implements (mud and moisture resistance), pumps and blowers (balanced radial/axial capability), and gearboxes (stable performance under variable loads). The double-sealed design helps extend grease life and minimize maintenance, while the deep groove architecture ensures efficiency at speed.

Key competitive advantages include precision raceway finishing for reduced friction, low noise grades suited to industrial motors, and consistent seal compression for reliable contaminant exclusion. Options such as C3 clearance, P6 tolerance, and application-matched greases allow tailored performance. Backed by Xingtai Botong Machinery Technology Co., Ltd’s engineering support, batch-to-batch consistency, and rapid lead times, B2B buyers gain dependable supply continuity and simplified qualification for OEM and aftermarket programs.

Cost, Maintenance & User Experience

Total cost of ownership for the 6306 2RS High Quality Deep Groove Ball Bearing 30X72X19 is driven by uptime, grease life, and changeout interval. The sealed design reduces relubrication demands and helps stabilize performance in contaminated or wet environments—lowering unplanned stops and labor costs. Standardization on a common size also streamlines inventory and purchasing across multi-site operations, improving cash efficiency and simplifying forecasting.

Industrial customers report quieter operation in motor drives, improved cleanliness around housings thanks to effective seals, and predictable replacement cycles that align with planned shutdowns. In Basic component manufacturing lines, maintenance teams value the bearing’s drop-in compatibility, readily available clearances, and consistent seal quality that supports longer intervals between inspections. Partnering with Xingtai Botong Machinery Technology Co., Ltd adds value via technical guidance on clearance/grease selection, packaging to prevent storage corrosion, and flexible MOQs that fit OEM and MRO purchasing strategies.

Sustainability & Market Trends in manufacturing

Manufacturing trends emphasize energy efficiency, reliability, and responsible sourcing. Bearings play a pivotal role: lower friction translates to energy savings, while durable seals and stable metallurgy reduce premature failures and scrap. As electrification and higher IE-class motors expand, demand grows for low-vibration, low-noise bearings that maintain performance under extended duty cycles. The 6306 2RS High Quality Deep Groove Ball Bearing 30X72X19 aligns with these trajectories by combining efficient raceways, robust sealing, and long-life lubrication strategies.

Xingtai Botong Machinery Technology Co., Ltd is investing in process improvements and quality systems that support sustainability goals—such as optimized heat treatment control for energy management, recyclable packaging options, and supply chain transparency. For B2B decision makers, this means a partner that balances cost competitiveness with forward-looking product development and responsible operations, helping you meet performance KPIs and corporate ESG objectives simultaneously.
