What Is a Ball Screw and How Does It Work?

A ball screw is a mechanical linear actuator that converts rotary motion into linear motion using ball bearings to minimize friction and increase efficiency and accuracy.

What Types of Ball Screws Do You Offer?

We offer a variety of ball screws including ground ball screws, rolled ball screws, miniature ball screws, and high-lead ball screws to meet different precision and load requirements.

How Do I Choose the Right Ball Screw for My Application?

Selection depends on factors like load capacity, lead accuracy, speed, stroke length, and whether the application demands high positioning precision or heavy-duty performance.

What Is the Difference Between Ground and Rolled Ball Screws?

Ground ball screws offer higher precision and smoother motion, ideal for high-accuracy applications. Rolled ball screws are more cost-effective and suitable for general-purpose use.

What Maintenance Is Required for a Ball Screw?

Regular lubrication is essential. Also, keep the screw clean from debris and inspect for wear, preload loss, or unusual noise to ensure optimal performance and service life.

24780 Bearing: Reliable Tapered Roller Solution for Heavy-Duty Applications

Sourcing the right 24780 bearing isn't just about matching dimensions. It's about ensuring your equipment runs without unexpected downtime. We've handled thousands of orders for this specific model—commonly paired as 24780/24720—from automotive rebuilders in the US to industrial outfits in Europe. Over the years, we've learned what separates a good bearing from one that fails under real-world loads.

Take a typical procurement scenario. A Midwest machine shop calls us after their supplier quoted lead times stretching into months. They needed 24780 bearings for spindle rebuilds, and the old ones were pitting under radial loads. We shipped from Shijiazhuang within a week, complete with test certificates. That's the kind of reliability importers expect when dealing with cross-border suppliers like Hebei Yidi Import and Export Trading Co., Ltd.

YIDI Motion started in 2020 focusing on linear motion components, but our bearing line quickly became a cornerstone. We produce 24780 bearings using chrome steel GCr15, precision-ground to ABMA standards. No shortcuts. Our German-imported grinders and Japanese heat-treatment lines keep tolerances tight—inner diameter at 50.000 mm nominal, outer at 107.95 mm. Buyers often ask about preload; we recommend checking your shaft fit first to avoid binding.

Why Procurement Managers Turn to Us for 24780 Bearings

Procurement risks hit hard in bearing buys. Lead times drag. Quality varies. Suddenly, your production line stalls because a "bargain" 24780 bearing from an unverified source flakes under load. We've seen it—vibration analysis reports showing brinelling after just 500 hours.

Our edge? In-house testing. Every batch of 24780 bearings goes through radial load simulation up to 80 kN dynamic. Static capacity hits 95 kN. That's real data from our lab, not marketing fluff. Importers appreciate this because it aligns with ISO 281 life calculations. Expect L10 life around 5000 hours at moderate speeds, depending on your lubrication setup.

Short observation: Many US buyers overlook customs classifications. HS code 8482.20 for tapered rollers keeps duties straightforward. We handle the paperwork, including CO forms for Canada or Mexico.

24780 Bearing Technical Specifications

Here's the breakdown buyers reference most. All measurements in imperial and metric for US and global teams. We stock both single-row configurations and can assemble sets with 24720 cups.

Parameter	Metric	Imperial
Bore Diameter (d)	50.000 mm	1.9685 in
Outside Diameter (D)	107.95 mm	4.2500 in
Cone Width (B)	25.400 mm	1.0000 in
Cup Width (T)	24.600 mm	0.9685 in
Dynamic Load (C)	80 kN	18,000 lbf
Static Load (C0)	95 kN	21,400 lbf
Material	GCr15 Chrome Steel	GCr15 Chrome Steel
Precision Class	Class 0 (ABMA)	Class 0 (ABMA)

Note the contact angle—standard 15 degrees for this series. Works well in combined radial-axial setups. Always verify your housing bore; we've had returns from mismatches by 0.01 mm.

Common Applications for 24780 Bearings

Agricultural machinery—tractors and combines handling shock loads.
Automotive axles, especially heavy-duty trucks.
Industrial gearboxes where space is tight.
Material handling equipment like conveyors.
Construction gear—excavators and wheel loaders.

One client in Texas uses them in oilfield pumps. They run at 2000 RPM with EP2 grease, hitting 10,000 hours before rebuild. Practical tip: Monitor for spalling if misalignment exceeds 4 arcminutes.

Advantages of YIDI 24780 Over Standard Options
