GRW high-precision ball bearings feature a packaging system built around three core principles: protection, traceability, and application-specific adaptability. Every package is clearly marked with the bearing’s exact design specifications, product lot number, factory batch code, and packaging date, ensuring full visibility and traceability from production to delivery. Below is a detailed breakdown of our standard packaging options and their key parameters.



Strip Packaging “CP”
Best suited for: Standard small-to-medium precision bearings, optimized for automated assembly lines.
Structure: Each bearing is individually sealed in a transparent synthetic film packet with a white backing, then arranged in a continuous strip or pill pack. This isolates every bearing, preventing cross-contamination and damage during transit.
Quantity per strip: The number of bearings per strip is determined by the bearing’s outer diameter, with standard quantities set to balance compact packaging and adequate protection.
Key benefits: Individually sealed units eliminate risk of scratches or dirt buildup, while the strip format streamlines handling for high-volume production environments.
Vacuum Packaging “LL”
Best suited for: Large-quantity orders, long-term storage, and multi-step shipping.
Structure: Bearings are bulk-packed in transparent synthetic film bags and sealed under vacuum, removing air and moisture to minimize oxidation and corrosion risk.
Quantity per pack: Standard pack sizes are based on bearing dimensions, but custom quantities can be provided upon request to align with customer inventory or order requirements.
Key benefits: The vacuum seal provides a stable, low-moisture environment ideal for long-term storage, while the clear material allows easy visual inspection of contents.
Spindle Bearing Packaging “CP1P”
Best suited for: High-precision spindle bearings and other premium, ultra-high-accuracy products.
Structure: A two-layer protective system: each bearing is first sealed in a GRW-branded envelope (CP1), then placed in an individual cardboard box (CP1P).
Protection features: The outer box provides robust defense against shock, vibration, and handling damage that could compromise the bearing’s precision. It also prevents mix-ups between different batches or specifications.
Key benefits: This specialized packaging ensures that spindle bearings arrive at the customer in the exact same condition as when they left the factory, preserving critical tolerances and performance.
Special Packaging
Best suited for: Custom requirements, non-standard bearing designs, or unique customer applications.
Available options: GRW offers a range of custom packaging solutions, including stick packaging for long, thin bearings, aluminum envelopes for special environmental needs, and custom labeling or quantity configurations.
Customization flexibility: All special packaging adheres to GRW’s core protection standards, and can be tailored to meet specific automation equipment, storage conditions, or logistics requirements.
